I happen to have a idea that can help out the server, A way to disable and enable /tpa so there can be no tpa troll to come at you and grief your unclaimed land or just to troll you and annoy you all day. It just gets really annoying to see /tpa trolls to only find out they will grief you. So please do this idea, It will help out the Survival server. Thank you.
I personally don't think there should be an enable and disable for /tpa for this reason because you don't have to accept it. It's a request to tpa, not an auto teleport. You have the choice to accept or not so if you don't want people trolling, don't accept the tpa. Maybe for people who Spam /tpa it would be nice but not this reason. Thats just my opinion though.
