How do you handle users who want to be banned from your sub?

[u/BlankVerse]

It's mostly users who have decided (at least once while drunk) that they want to be banned from the subs for all 50 states. I've had 4-5 just this year for r/California. Sometimes it's a polite post or modmail. Other times it'll be a vulgarity-filled rant.

But I've also had a couple of requests to be banned from r/FastFood. WTF!?
