I'm not very familiar with the ban-hammer of Bliz. I do not know their procedures.
But this sounds like someone's name got on the wrong list some how:
Just voicing my support to the request that more effort be spent looking into this and hopefully explaining why Laama got banned and giving him a path to redemp-un-banning.
I agree with Kirk that the bans were necessary and I do not think they should be rolled back straight up. I am only requestion appeal.
