Social media pushes the type of content OP is talking about. Content with interesting/clickbaity titles is rewarded on every social media website. This leads to doomscrolling.

What do you mean by whom? By everyone who is part of creating platforms like these. The most boring social network would be a telephone book.

Notifications, upvotes, likes, feeds, algorithms, subscriptions… are all designed to keep you hooked.

Is there really a doomscroll-free community, besides maybe the mental illness communities? All social media is designed to be addicting.
