Since Lemmy doesn’t have a lot of content yet, I primarily browse all. Since there are a lot of active communities in all that I’m not interested in (different language/NSFW, etc), it would be really handy to be able to block them from the ellipsis menu. Right now you have to go I to the community and find the block option there. Similarly for users.
It isn’t strictly equivalent, as filter only works on Sync, whereas block is a Lemmy account feature. If you only use Sync though, filter is great.
To add to this, you can filter instances, but you can’t (yet) block them.
That computes. I hope instance blocking comes to lemmy as a feature eventually 🤞
