God, where do these guys get this shit?! It's fucking disgusting. Seriously, how does a guy come across this stuff unless he looks for it? Disgusting, degenerate, anti-social homosexual bastards.
How did you come across this stuff? Where you looking for it?
Maybe he found it the same way, jackass.
Also if you've ever heard of rule 34 you know that when you do a Google Image Search (GIS) for seemingly innocuous terms you can wind up with some freaky porno results. I'll help you out try this:
http://images.google.com/images?q=craigslist That's right search Google for images related to Craigslist and first page has porn results (craigslist may be a bad example, but the words aren't strictly porn related, not like Giant Cock Anal)
