Basically as what I see is this:
infaMou$
nick is banned in JB on the same day for banevading who is assumed to be
beBo$$
When I check both nicks in gametracker for JB I only find beBo$$, but not infaMou$. So would that be a real coincidence that right after your ban you joined with your other account and thought you could get away with it?
Making up the story that this is your cousin, WHICH doesn't even play JB. Either way we do not accept such reasons.
