http://dota.eurobattle.net/la/forum/index.php?topic=170651.0you didn't get banned for chatting, chatting is allowed.
You got banned for hard family flames and national intolerance which is not allowed and never was allowed nor will be allowed.
from rules:
2. Player must not insult:
c: Insults which contains family members may be considered as "family related flame".
Note: This also applies for insults via whisper.
I highly suggest you change your attitude and behave normal, take this ban as your last warn, next time it will be permanent.
if you STILL got something not clear here feel free to send PM to efko.aqw he is section admin and he will deal with this complain of yours.
