Maybe it doesn't "look good" but he is my friend, and there is no rule saying i shall get banned for that. ESPECIALLY established last time someone played with him nobody got banned. so i thought, hey who gives a shit lets play some 2v2 but if you cheat, i don't wann play with you. And let's not deny the fact seeking was top 5 worldwide player by the time he got banned without cheats, we could all witness it on ml finals, and also i feel his skill, that's personally the reason i play with him in first place.
His skill isn't the issue here. It's more the fact that well he's banned, you're playing with someone who's doing a ban evasion and is thus breaking the code he agreed to when he bought the game. You're playing with someone doing this deliberately.
HOWEVER
I believe crossfire,artavick and legio who did the exact same thing while in a tournament without punishment should also be held accountable because it's the exact same thing except you're getting punished for doing it.
