I can't speak for OPs motives or have ever been banned by Blizzard but players should post this everywhere.
Companies do ban players for no reason and often don't wanna do anything about it, so negative publicity like this, if it gets out of hands will force them to rectify this or at the very least provide proof aside from the usual "out detection systems are perfect and can do no wrong" bs.
Or at the very least, if the ban was issued wrongly and posts like this discourage even 1 person from buying the game... a small measure of revenge.
