There are unfortunately some subreddits which are still the best place to find timely info about certain topics - for example video game subs run by the developers of the game. Lemmit is a way to subscribe to those while not giving Reddit any more “engagement” or ad views.
The bot that runs Lemmit only posts on its own instance, so users like me only see it when we subscribe explicitly (or the All view I guess, but that’s a mixed bag already. Edit: and each user could choose to ban it if they want)
If it only reposted a small amount from niche subs then that would be different, but it completely spams the whole of Lemmy with zero-effort content that no-one interacts with. Makes browsing ‘all’ unpleasant for everyone else, even if you don’t like doing that yourself. And if you think one spam bot is acceptable, then where do you draw the line? Ten? A hundred? Should we make the effort to individually ban all of them ourselves?
