Nice joke dude. A 18 years old account and 157 hours in TF2. Very weird. It should be your main account since it's an old ones. I don't think you've an alt with thousand on hours on it.

Also type "shounic tf2" on youtube and watch one of his last video about bots issues and TF2.

Almost playing this game since 15 years on a daily basis, you know nothing about the bots problem, let me tell you.
