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)
I guess we just have different opinions on things like how much ‘effort’ it represents, how important it is that people interact, etc.
I feel like Lemmy will very soon be at the point where the All page isn’t going to be useful to sort by New (if it’s not there already) so minor cleanups like banning Lemmit aren’t going to make much difference. Switch it to something like Hot and I’m sure it won’t show up much at all, nor other “spam” bots.
