You clearly abused your donation commands and the pvp zoning here, and I don't see how you could have ever thought that this was fair use. This is common sense, if nothing else, and in no way could the player who /tpaccepted have known what accepting it entailed.

I will be speaking with some other staff before I decide exactly how to proceed.
