We don't need any new rules or restrictions to clean up this mess, but rather we just need to enforce the ones we already have.
It's not easy (nor practical) to enforce the current rules. As long as someone incentivizes Joe to earn few bucks by copy-pasting articles to the Press board, it's pointless to continue reporting. Even if both sides, you as a member and the moderators, report and delete frequently, this mess isn't going to be tackled. It's like squashing the water.
What we do need is a radical change which will retain free speech, but will, alongside, discourage those users from shitposting.
