Anonymous internet forums will very likely die out if inference gets another order of magnitude cheaper.
The only solutions are (1) private forums, (2) strict verification or maybe (3) some sort of "web of trust" thing, if someone manages to make it user friendly and not suck.
I agree and my bet is on private and semi-private (invite only) forums making a come back. It is so much easier nowadays with so many Ansible playbooks and Dockerfiles to automate things.
