I guess it's achievable with hosting you're using (with nginx ip block list for example if you're using it)
If theyβre using Cloudflare it can do this too. Even the free tier, you can have one monstrously long WAF rule to ban a bunch of IPs
What you're looking for is functionality like fail2ban, but probably with a filter set to the HTTP endpoint for creating communities. Not sure if it will work, I haven't really looked into the Lemmy code/architecture yet.
