i started using the internet in the late 2000’s and still remember when you search for something most of the times it would return with a forum post … now its just random websites … if you ever need real and concise answer you have to add site:reddit.com at every search and since discord or twitter are not crawlable by these search crawlers they are not mentioned . Where did all those forums went…are there still active forums ?
It’s an inherent problem with the way federation is designed in the Fediverse. Since all content is replicated, this includes stuff like CP. If the admins wouldn’t defederate after learning about it, they’d willingly host it, making them legally liable.
