There's probably a couple of things you can do...

* You could change your ports to "less used" ports - it doesnt stop them, but means they need to do more work to find the port you are using. I've never been in favour of this option.

* You could put something like haproxy in front (which is what I do), with haproxy you can use default ports (or not), but put in rules like 1 concurrent connection from the same IP address, 2 connections in the last 60 seconds, add a CIDR list to exclude IP address ranges (although I do this on my firewall).

It doesnt stop them, but sure slows them down.

* Another things I looked at and there are pro's and con's, is having your BBS behind a VPN of sorts. I've played with zerotier and yggdrasil, and then limiting inbound connections from other users who are also inside the VPN.

Sadly, for this to be useful, its almost an all or nothing approach (we all use it or not). Since we are all mostly sysops (and few adhoc users) its doable.
