So I purged myself, because I needed to retest plugins, and it said that that command removed all of a player's quests data... You forgot to mention it blacklists them as well. I tried removing myself from the blacklist in the config.yml, but everytime I reload, it just adds me back. Can you please tell me how to fix this?

It should not add you back. Stop your server, make sure it's your UUID you're removing, then delete that line and save before starting your server. Make sure to actually /stop your server - a /reload may not be sufficient.

Closing due to lack of response.
