Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi, as the subject said, I was just playing with a friend and I got banned (the fact is that my friend isn't ban at all even if we did the same quests / travel / etc...) so I just searched for an answer and all that i can say is that :

-I talked on the general channel
-I was installing Questie.

Even if I'm not unban i just wanted to know the reason of this one in order to play correctly next time.

The names are Sreexeroni / Sreexerino , a hunter and a rogue.

Thanks for any answer that may come.

Thanks for the fast answer.

for anyone who was concerned, I just dled something that look like a keylogger among the questie's folder.
