The other stuff is repulsive, but only the Atlas stuff should matter for banning on Atlas.
I mean, if I went over to Ben's house and beat him up, I don't think I should be banned here
But I find it repulsive that BRTD's implied attitude is that it's no big deal since it happened to Ben. Instead of trying to argue it wasn't really hacking to figure out my password and read my private messages and send messages out from my account, I would instead suggest advocating a more moderate punishment on Xahar than permanent banning.
And yes it is hacking
