Those Stack Overflow answers are awfully contrived. In my experience answers like that are quickly down-voted and deleted by the community. That being said, if you ask how to parse HTML with regular expressions, or post some SQL with injection vulnerabilities, they'll be closed as duplicates.

Yeah, I believe him when he says it happens, but I've never encountered hostility on SO, and I've asked some really stupid questions (and in each case, I really ought to have known better and done my homework, so in my case I would have deserved a bit of condescension).
