You will still get a message for them, so if they're being annoying you will want to block them anyway, but at least it won't clog up the game.

Not complex because we aren't sending anything that isn't easily accessible via the Master Server anyway, just means we aren't sending plain-text IPs to Discord. Might be improved by basing the XOR key on other values (base RNG, maybe version) so that it's not like *right* there
