social media is only bad if you don't curate what you're looking at. most the platforms these days have features to block posts containing certain words or hashtags.
i've made a lot of great friends using social media over the years both where i live and in other countries.
Please. I have an extensive file with tags I've put into use to "curate" content on mastodon and bluesky. It works somehow on mastodon but the "main" server in their admins wisdom decided recently to remove live feeds to make experience supposedly more appealing. And now users are limited either to trending or manually searching posts or browsing by tags. They seriously limited exploration and interaction with new content there.
Bluesky on the other hand still serves me the content I tried to block or filter out. And whenever I go into other feeds in the end I'll be flooded with never ending stream of x-rated drawn content that I don't want to see. Interests set or not - I can't escape that stuff. My partner complains for same things.
Facebook in my last days there decided to limit posts from my friends because I wasn't active enough to feed the algorithm, and instead filled main activity stream with generated graphics. Instagram was somewhat fine up until bought by facebook - after that interacting with any content would poison your stream with stuff for months.
Reddit has become an interaction and content clown show once they started pushing for this "modern" interface. I won't create there account ever again due to how they started treating their users.
So there's this "curation" for me.
It's bad because you can't curate it. For example on fb there is no way to disable reels.
Most social media is actively against that, feeding you recommendations to keep you on the platform.
