TBH I just stick to the feed and block the communities I don't want to see. Especially avoid anything on Hexbear or lemmy ml, those instances are CCP propoganda trying to convince the west to off each other and themselves.
I see so many comments like this across lemmy and so little offensive content from those instances that I'm really beginning to wonder who the actual propagandists are.
The block feature only hides posts from those instances communities, not comments (unless you block individual users, but then you have to block a whole lot of users).
Also users from those instances will still have an influence on your feed via their voting. For example if you think an instance is a source of political propaganda, they can still promote that political agenda via voting.
Defederation is a more effective solution if you want to avoid an instance.
