Not sure if the feature has been requested but I’d love to filter some out if possible!
Came here to ask this, too. Desperately needed. My feed is full of furries and incel nonsense (and, at the moment, beans, but beans are cool).
Not yet, no.
Personally, I’m using a combination of the app and being logged into my instance with a web browser to get what I want done (the app for browsing, upvoting and replying, and the browser for more ‘back-end’ stuff like creating/editing communities, and blocking instances and communities)I’m doing the same. The app is great for browsing, and I don’t need to do the backend enough to get annoyed at the switching.
I’ve also found the search in https://lemmyverse.net to be a lot more forgiving/useful than the one on wefwef for now.
The search function on wef is really buggy.
