Social media has censorship, which most old school forums couldn't simply replicate with volume, even with moderators in place. So, a lot of times you will find unfiltered discussion about certain topics as opposed to a controlled narrative you will get on social media.

Old school forums would definitely ban you for bad behaviour. Comments like "Dumbass XD" that you would see on X all the time, will simply be removed.

Old school forums were also regulated by reputation, which means people had to put effort into their posts. This discourage low effort trolling and rage bait. If you had some crazy takes, people will eventually make fun of you. There was a time on 9gag where it was flooded with anti-trans posts. That could never happen forums, because people would ask why OP is so obsessed with trans people.

Lot of forums would even solve it by having anything goes sections.
