he did a chargeback on donations so fuck that guy, no refunds, he really fucked things up for everyone, for his enjoyment. ban him, you don't need that. and if you find out he has another account ban it too. don't provide services to people who shit on you.
i'm also reading he collected the donations to donate to you and charged those back to keep them for himself? again, ban him and move on.
plus he's messing with your staff, "doxing" (whatever that is), and "exposing" them? that's crazy ex girlfriend level shit. again, ban him and move on.
anyway, you guys are the best, i'm only posting criticism because i assume you want it, since you posted this all in the forums. i'm a huge fan of the project.
