Reading through this thread and others
like it I noticed that they all seem to be based around the same misconception that whatever changes happened to codex are entirely external. A.k.a its not the world of 2005 and 2021 are two different worlds with different sets of relevant discussion, its those filthy GG refuges/pol/acks or some other nebulous group that just sorta spontaneously showed up on the site. Its not that topics that used to have 0 overlap now have a massive overlap, nope its just angry shit posters and nazis. If only we could get rid of them all then time would reset and it would be all like it was back in
"the good year of choice".
The sad part is that this is not only wrong for obvious reasons but also because it historically never actually worked. Not for forums, not for image boards, not for news websites.
Oneangrygamer.net was infamous for its "edgy"(read 2005 libertarian) content yet while it was this edgefest of a site it had massive success and plenty of traffic each day, with sometime hundreds of comments under the more popular articles. Then it was sold off and despite a complete re-brand nobody cares. The site is effectively dead with comment sections gone and basically 0 traffic.
Similar thing occurred with Neogaf where despite all the concessions made the site was hard booted of the net after the owner was accused of sexual misconduct(accused proved to have committed, keep that in mind). The only reason why the site did not disapear into the memory hole is because the management momentarily understood that getting good boy points from journos might warm their hearts but it leaves their sites empty and balance at 0.
Same thing actually happened with 8kun.top. Where the moderation got the bright idea to first kick out the GG crowd because "they were shitting up every thread" but then also pushed out anything to do with politics to promote its custom brew "news" board and as a finishing blow even managed to chase out the l*li degenerates. That place is currently a ghost town with the most active boards being a Qanon larp board and hypno-sissification board. Also no one bothered to exonerate it for all its valiant effort in any way shape or form and its to this day considered and unclean site.
Point being chipping away at your community for any reason will never bring you anything. The media and developers will not just flock to you for being a good boy and nobody will be exactly giddy about joining a forum/site where they face the risk of being removed en masse whenever they become slightly inconvenient.
