I humbly suggest you to add info in this plugin about whitelisting too, if it's possible :)
I read your previous comment somewhere upthere saying it is not an easy task, but:

I'm on minnowbuster's blacklist for some reason. (I asked on dedicated discord channel to be removed from list, but I was ignored. Frankly, I do not care much.)

On the other hand, I was honored to be added to @ocdb whitelist because my art was apparently good enough. And you know, you've got to earn this privilege, it can't be bought.
So... that is that. Being on someone's blacklist doesn't determine being an asshole. Not always.
Anyway, good idea, good plugin, Cheers!
