What's your IP address and which DNSBLs (RBL is a trademark of MAPS LLC)
are you referring to?

That's more likely to get you permanently plonked than removed.

That makes more sense.

That's a pretty dumb thing for them to do, I'd have to agree.

That's fine: your mail server, your rules. However, if they did
eventually make a query regarding your removal request, you probably
wouldn't want to reject it.

A workaround might be to route outgoing mail for domains using that list
via another mail server, such as your ISP's mail server.
