I'm happy on feddit.de, as they are really only defederated from the tankies and Threads.
I left L.W when they federated with Threads and tried lemm.ee, but dealing with the tankies is so annoying I had to find another new home and settled for feddit.de.
Yeah lemmy.ml has gotten worse with tankies, but it's no where near as bad as the others. And I still want to see some lemmy.ml communities (tech, gaming).
But unless it's changed with some of the recent updates, blocking instances as a user (on lemmy) only blocks posts from the instance but still allows interaction with their users in comments of posts. It's different for kbin and mastodon.
I don't want the annoyance of arguing with tankies from their main instances. I'd rather be defederated.
Also, why go back to lemm.ee and do that when I don't need to on feddit.de? That seems kind of silly in the first place.
Did exactly the same thing a while ago. I'm sure at some point I'll also have to make an account on just that instance so I can view it there which is shitty but works.
