Yes, but a new user needs to know the instance they join has pros and cons. Like another user stated, they joined .ml after lemm.ee closed and didn't know why several communities they had subscribed to weren't showing up.
Let's be real for a second, lemmygrad, .ml and. hexbear are well known for blocking and being blocked on Lemmy. Users should know Lemmy isnt like reddit where each user can potentially see 100% of content, it's dependent on your instance.
