TripAdvisor has defended itself against accusations of misleading travelers by failing to stop some of its highest ranked hotels winning their status with fake reviews.UK consumer group Which? Travel analyzed a total of almost 250,000 reviews for the 10 top-ranked hotels in 10 global tourist destinations, from Las Vegas to Cape Town. It found that one in seven of the hotels had "blatant hallmarks" of fake reviews, with others raising "serious concerns."But TripAdvisor called the analysis "flawed" and said its more sophisticated detection tools were able to weed out fraudulent feedback.Which? Travel said that when it reported 15 of the worst cases to TripAdvisor, the reviews giant -- now one of the world's biggest travel websites -- admitted that all but one of the hotels in question had been caught using fake reviews in the past year.Six had previously been penalized, and two had received a "red badge warning" -- where TripAdvisor warns users that the hotel is suspected of using fake reviews, and has "repeatedly failed to remedy its behavior and refuses to cooperate with TripAdvisor's investigators."Yet, Which? Travel said it found that the review patterns had continued unabated despite the measures, and the red badges had been removed.The group has accused TripAdvisor of a "lack of serious ongoing action to address repeated abuse of the system."It says that five-star reviews left by new users who have written no other reviews should be a red flag. Its analysis compared the proportion of first-time five-star reviews with that of first-time three-star reviews, which are less likely to be faked.In total, it studied 247,277 reviews."TripAdvisor's failure to stop fake reviews and take strong action against hotels that abuse the system risks misleading millions of travelers and potentially ruining their holidays," said Which? Travel's Naomi Leach.TripAdvisor has removed hundreds of reviews in light of the investigation, Which? Travel claimed."Striking" evidence of fake reviewsHotels in the Middle East had "striking" amounts of fake positive reviews, according to the research. TripAdvisor docked 730 five-star reviews of the "best" hotel in Jordan following the analysis -- but the hotel has not been given a red badge. It remains in the top 10 in the country.At the top-ranking hotel in Cairo, 79% of five-star reviews came from one-time contributors. Just 14% of three-star reviews came from similar accounts.The hotel has lost its status as a result of the reviews' deletion.Las Vegas was another hotspot for fake reviews. At two of the top-rated hotels, almost half the five-star reviews came from one-time contributors. For a competitor which did not arouse suspicion, the figure was just 3%.Some of the top-ranked hotels in London, Paris, Barcelona and Cape Town "gave reason for suspicion," the research showed, but failed to demonstrate the same patterns across the board.Repeat offendersTripAdvisor called the analysis "based on a flawed understanding of fake review patterns," adding that "it is simply far too simplistic to assume all first-time reviewers are suspicious."It said that Which? Travel did not have access to IP [internet protocol] information or location data, both of which TripAdvisor uses to detect fake reviews."We analyze hundreds of data points about each review -- most of which only we have access to -- and we combine that data with a wealth of knowledge and understanding of review patterns that our team of experts has gained from tracking hundreds of millions of reviews over a near 20-year period," said the company."This includes an ability to track and analyze first-time reviews in far more detail and with far more rigor than Which's team was able to do."Online reviews influence an annual estimated ￡23 billion ( billion) of booking transactions in the UK alone, according to the UK government."Sites like TripAdvisor must do more to ensure the information on their platforms is reliable," said Naomi Leach."If they continue to fall short, they should be compelled to make changes so holidaymakers are no longer at risk of being duped by a flood of fake reviews." 4152

Treasury Secretary Steven Mnuchin on Thursday encountered a blitz of questions from House Democrats seeking to establish a legal basis for requesting President Donald Trump's tax returns.It was the first time Trump's top finance chief, a close ally of the President, was forced to publicly address the unprecedented issue of whether he would comply with an obscure law that may require him to turn over his boss' tax returns, if a formal request is made by Massachusetts Rep. Richard Neal, the Democratic chairman of the House Ways and Means Committee.Throughout a more than two-hour hearing on Capitol Hill, Democrats asked Mnuchin to state exactly how he would handle such a request, which the secretary carefully tried to side-step, at one point, even jokingly noting, "There's a lot of interest in 6103 today" -- a reference to the tax law.Mnuchin told lawmakers he would obey the law if he receives a written request from Congress to turn over Trump's tax returns -- but also suggested that the decision to release the returns would fall to the commissioner of the Internal Revenue Service, the country's federal tax collector.Trump has refused to release his tax returns, 1190

This year, voters in 31 of the nation’s 100 largest cities will choose a mayor in municipal elections that historically don’t garner the same numbers in terms of voter turnout as presidential elections.But the makers of a new smartphone voting app think they can make it easier for people to vote. This week, Denver became only the second place in the country to ever allow voting by smart phone.It’s called Voatz. Yes, a weird spelling, but it’s a straightforward concept: it’s an app for voting. “To get through verification, they have to take a ten second selfie video,” said Jocelyn Bucaro of Denver’s elections division, who says the app utilizes an individual’s biometric data—like face recogmition or thumbprint technology. “They have to look at the camera, they have to blink, move their head, so that the system knows it’s not a video of a photo," she said. Bucaro thinks that one day, this will be how we’ll all cast our ballots.“If we want to maintain a democratic system and have as many people participating as possible then some form of this will likely be available for all voters," Bucaro said.Right now, it’s just available for active duty military stationed overseas. But there’s a reason for that. Currently service members have to print, sign, scan, then email the document to election officials.Former FBI cybersecurity expert Andre McGregor said that made them the perfect group to pilot the technology.“When you compare it to the current, everything is better than a PDF sent via email, even fax is better than that,” McGregor said.McGregor is talking about the obvious concern with a voting system like this: security, something he says he was concerned about at first, too.“I had just as many skeptical thoughts as most other people thinking about the idea of voting on a device that’s in your hand.”McGregor looked into the potential pitfalls of the app before it went live with West Virginia’s military voters last year, and the app, which uses block chain technology, exceeded his expectations.He says trying it out on small groups is a good way to make sure it’s ready to go mainstream; disabled voters might be next to try it. 2168

They're the hallmark of vaping — the massive clouds that sometimes come in different shapes.But how does a little e-liquid become those clouds?We're going inside an e-cigarette to find out.The devices usually have four main parts: a reservoir that holds e-liquid, a battery, a heating element and a mouthpiece.The first step is to add e-liquid to the reservoir or to attach a pre-made cartridge.The liquid is made of nicotine, flavoring, vegetable glycerin and propylene glycol. You’ll find propylene glycol in things like inhalers and fog machines. The U.S. Food and Drug Administration says it’s all safe.Next, the battery warms up the heating element and that vaporizes the e-liquid. The vapor travels through the e-cigarette, out the mouthpiece and into the lungs.When exhaled, the vapor vanishes into the air fairly quickly.The heat is low enough that it doesn't combust — or burn — the liquid.Supporters say vaporizing creates fewer dangerous compounds than combustion.The American Cancer Society says vapor can still contain harmful chemicals or substances, like volatile organic compounds, or VOCs.They cause inflammation and can make the kidneys, liver or nervous system fail.According to the American Cancer Society, vapor can also contain harmful flavoring chemicals and formaldehyde. 1312
