>>susam+(OP)
IMHO, any social network that offers an "explore" section (i.e. a feed of strangers' posts) is doomed, independently of whether it is algorithmically filtered or chronologically. I ultimately dropped Mastodon because the "dumb" feed from my instance was already enough to waste my time.
To prove this, just use Instagram or Facebook from your browser with the proper extensions and they'll stop being absolute worthless time sinks
