    Most people don’t have static IP addresses, so banning their IP will only stop them temporarily. Then whoever gets that dynamic IP address next will be banned too. Then there’s CGNAT where 1 IP address can have up to 128 people using it at once and the address changes even more frequently.

      We’re talking about temporary bans here, which do work against spam. Private users do have dynamic IPs, but at home I think I’ve had the same IP for years. They don’t wildly switch them around.

      On second thought the IP is probably not federated though, so if there isn’t a common IP block list which instances subscribe to it won’t work.
