Does anyone know of filters that work on IRC content, *à la*
SpamAssassin?

What are you trying to filter?

Mostly:

* random spam (typically for crypto-currencies, but I've also seen
spam for pyramid schemes, etc.);
* a few trolls with scripts and bots that join channels just to print
gibberish.

I guess you could set up fail2ban rules with your irc logs?

“…typically for crypto-currencies, but I've also seen spam for pyramid
schemes…”

This is redundant. :-)

If you want to filter the spam before it's forwarded to other users,
it needs to be integrated with the IRCd, so you need to tell us what
IRCd you use. For example, [see this for UnrealIRCd](https://www.unrea
lircd.org/docs/IRCOp_guide#Fighting_spam_and_drones) or InspIRCd's
[filter module](https://docs.inspircd.org/3/modules/filter/) and
[dnsbl module](https://docs.inspircd.org/3/modules/dnsbl/).

You can also use your own bot, such as
[ozone/Sigyn](https://github.com/Libera-Chat/ozone) which is an oper
bot, or [ChanTracker](https://github.com/ncoevoet/ChanTracker) which
only needs to be op in channels.

Another option (though it does not work like SpamAssassin) is to
require registration (with a valid email address) before chatting; but
it can be disruptive for your actual users.
