:/ There's also the opposite with elitist people who bought the game booting everyone who doesn't have the proof-of-purchase hat from their server. I've seen a lot of complaints about that from a lot of people since it went F2P. But I guess I'd be more worried about ban evasion.
There's a plugin/mod called FREE2BEKICKED and it kicks anyone that is a free user. I have no problems with the free players because it's always fun to play as a spy.
Wow, I just heard about this! A few of my friends have been playing Team Fortress 2 and always pestered me to buy the game. I put it off and then I got into the CoD series. I'm pretty burnt out on CoD so I'll definitely give TF2 a go. It should be fun with so many of my friends playing it.
