The problem with the current system for player behavior.
So a few weeks ago i started leveling a new account. From level 1 -25 I did nothing but join a game and move my character every 1-2 minutes and pretend to fight etc, maybe pick up a few cs each time, all the while watching tv.
After lvl 25 or so, I start actually playing the game, But because I said a couple mean things I am banned, and now I am back to pretending to play games while watching tv.
TL DR: Its okay to essentially afk, so long as you dont say anything mean. This is completely stupid.
