I have a feeling that the only short-term solution is heavy content curation by the users themselves. Nobody is incentivized to do it for us. It takes time and effort but the only thing that has made any kind of difference is blocking everything you don't want to see. And I mean ruthlessly doing so. Someone replied with a clown emoji to this thread and they're now blocked. That's how petty I'm about it nowdays. The vast majority of users on social media just add to the noise and it's this group of people I'm trying to get rid of.

The way I think about it is by imagining a room with 100 random people. Do I want to talk with all of them? No. I'd rather talk with the couple most interesting ones among them and ignore the rest. I don't have the time and energy to pay attention to the constant feed of meaningless nonsense.

Block subs you're not interested in. Block users that dont bring any value. Add content filters for topics you're sick of reading about etc. You're not going to miss out on anything. You're not going to run out of content. You'll hardly notice any difference but after some time the signal does start to get stronger and the noise does quiet down a bit.
