I've never had a problem with social media usage - and I'd be surprised if other developers here haven't enacted their own solutions to prevent doomscrolling.

I have user scripts on both my iPhone and my computer that completely disable the Instagram recommended feed. I have disabled YouTube thumbnails and the YouTube sidebar. /r/popular or other popular subreddits get automatically redirected to my Reddit homepage which has a lot less garbage on it. I have completely disabled my Twitter feed. I even have certain domains removed on HackerNews and made an extension to only update a few times a day. And a ton more.

If you're a developer and you want to stop doomscrolling... you have the power.
