Yeah, there quite a few. Like old-school phpBB is still around[1]. Or, take a look at the list on Wikipedia[2].

Not sure if you're looking for a hosted solution, though. A lot of those would involve you running your own server.

How I miss my script kiddie days of being 15, downloading "nulled" versions of vBulletin off of Limewire and throwing them up on pocket money paid cPanel web hosting account waiting for it to upload on my parents 56K.

Exploit ridden PHPNuke & e107 CMS too.

We had similar childhoods - though I did phpBB. Never had an audience for the forum, but it was cool just having and styling it. Good times.

Discourse also has a (first-party) ActivityPub plugin now!
