Forums have mods and admins. As long as they don’t allow a topic habitually then, per my understanding for the UK law right now, that would make it exempt.

Compliance with the ID law is actually wrote expensive if you contract Persona as the ID checker. If 1 user of a site not based in tje UK or about UK things posting 1 news article a mod deletes in 10 minutes is enough to trigger a $50,000 compliance contact, then it’s enough to be amazing standing for an easily won lawsuit about burdens on small business.
