If you think that, you haven't played with ZX81 yet.

Seriously, if you need to keep a blacklist containing info about players, do it. That way you can go throatcutter on those players in future games and those comments can make you laugh instead of offending while you watch them being crushed. >:3 Nyah-hahaha! (By doing that you might run the risk of gradually becoming a troll, so be careful.) =^?_?^=
Just take your time, whenever you do something that makes the game harder for the others, you have a good chance of being called something like that. Just keep a thing in mind for later: "Payback time".
Wanna see my blacklist?
