Lately I've been getting a lot of weird friend requests from people who say something like "My friend wants to buy items from you" and then they post an obviously incorrect steam community link. I didn't click on those, because I'm afraid they might be hackers.

That being said, I'm only getting these dangerous requests because of Tf2Outpost; ever since I started putting up items for sale yesterday.
I can't help but think of all the people who might have fallen for it already... Isn't it the moderators' responsibility to make sure these people don't have access to the site, so they can't harass others?
