Here's another story about how you should never trust anyone you meet on Craigslist. Ever. A perp is accused of using 11 stolen credit cards to buy more than $80,000 worth of gym memberships at the Equinox in the Flatiron District. He then put them on Craigslist, where buyers shelled out between $600 and $1,000 for the memberships, which usually cost $2,800. But when the victims arrived at the gym for the first time, they were told their memberships weren't valid, the Post reports. Police were able to track down and arrest 21-year-old suspect Kedar Quashie because he purportedly used various aliases with different victims, but only one phone number. He was arraigned on charges of ID theft and grand larceny. Last month, a mobster reportedly Maced and robbed a man he first contacted on Craigslist.
