Yeah I agree for the most part. I will say I think moderation can have problems though (example: Reddit for a while did that thing where they would ban 1 fascist subreddit for inciting violence against minorities and then also ban 10 leftist subreddits for people saying John Brown was based).

But I think it depends on how the platform is designed and how moderation is implemented. Lemmy's implementation is some of the best I've seen.

But I do agree, some form of moderation is necessary.

Create your own Lemmy community on your own instance then.

unlike the others I see where you are coming at and it is also a bit of my dream. I would love to block or subscribe or throttle (give a rating that increases or decreases posts in the feed) at any level of individual, group, domain, etc. At the individual level I would like blocking to go both ways. I don't see their content and they don't see mine. I would like it to basically put us in different universes. I would like to be able to subscirbe to folks blocking lists. Im sure there is more that I have not figured out yet but I get where you are coming from.

I don't think that's feasible for anyone. Pretty soon your and every other user would be flooded with unwanted content, which will take time off all users individually to filter out. What this will result in is filterlists being made by community members, which the clients will use, some by default so that the system remains usable even for new users.

I don't see how that would make a meaningful difference.
I mean sure, technically now it's you who's filtering, but is it really you if 1. the filterlists are maintained by a 3rd party and 2. you don't have the capacity to audit all changes to the filterlists?
