There's no shortage of news reports about would-be pedophiles getting busted by undercover cops posing as minors on the Internet. So why do these men keep falling for it? Because they are sick puppies who just can't help themselves, we suppose. The latest alleged perv is an adjunct professor of economics at several city universities named Igor Sorkin. Prosecutors say [pdf] Sorkin, 31, sent sexually explicit messages and photos of his genitals to a vice officer posing as a 14-year-old girl online. He was arrested Tuesday when he tried to meet up with this fictional teen in Queens, and faces up to seven years in prison. But was the feedback Sorkin's received on Rate My Professors a red flag?

One student who took Sorkin's economic class was clearly smitten, describing the professor as "young, talented, smart, intelligent, easy-going, fun, with a great sense of humour :) You'll never get bored on his lectures. AAAAA take him take him!" Another described him as "very carefree," while a third pointed out that Sorkin was "always there to help and answer questions after class." Yeah, we bet he was eager to help out any young student who needed a special tutorial on, ahem, inflation.
