Based on this poll with 599 participants from the german !ich_iel@feddit.org community, most of us are somewhere between 20 and 40 years old.
This is only a small fraction of lemmy users, maybe it just represents the age range of german meme enjoyers on lemmy, but I don't know of any other poll with a sample size this big.
It takes a while. I waited a couple days for my confirmation mail to arrive. Keep in mind that Loops is being built by a single dev. If you read the toots by @dansup you'll see that it's a work in progress.
I don't think it's censorship necessarily. Their approach to combine similar communities into one club could be the cause and maybe they just haven't set up the c/fediverse club yet.
My post now federated to ClubsAll, comments seem to federate a little slower. There is no mention that this is content from lemmy.world and clicking on the fediverse "club" just gives a 404.
But I like fast music /s
