Are you all idiots? It's a great tool to boot hackers and even out team incase of leavers. It's only used badly if the user is an idiot. What you're trying to say is everyone and anyone who uses it, will use it the wrong way.
On top of that.. save a replay an send it to TDA.. wtf? Ok maybe if you feel like spending 5 mins after every damn game to save the replay and send it to TDA because some random pubber you'll never see again decided to leave, then by all means.. go waste your time with fruitless stupidity.
Custom kick is a great tool, I use it all the time and it's saved plenty of games from destruction since it's download. Lastly, if you use it to kick players that are better than you, you truely are a dirtbag.
