I feel for you OP.

It has gone done some on Mateus, but I used to park my character, turn on Camtasia, and record tons of bots in Gridania by the Twin Adder NPC in the HQ there. And yet ... nothing. Heck, I still have my blacklist full of bots and none have been deleted. So I'm assuming they "delete" the bots by just closing accounts but not deleting the characters ... which is stupid.
