First please don’t ban me I’m new.

lemmy.world, lemmy.ml , lemmy.xxx, lemmy.whatever, etct… + hundreds of clones. Is each of these a Reddit by itself containing many subreddits inside it?

Does that mean if someone in lemmy.xxx/c/jokes posted something interesting that I wont even see it because I’m signed up in lemmy.yyy/c/jokes ?

That is quite a weakness of lemmy compared to reddit. Can I post on lemmy.yyy if I signed up for lemmy.xxx or do I have to sign up for each of them?

Which one should I sign up for?

How can I see all lemmy posts in one place? I can’t believe no one has found a solution to this yet and just let hundreds of clones post repeated things. Also how is each moderated? Is lemmy.yyy moderated by sensitive snowflakes who ban anyone who cusses or offends anyone, while lemmy.xxx is ran by racist nazis? How does this work?

Edit: Thank you I read all comments and thank you some where very helpful. and I hope things get improved and added with time. here for the long ride
