if you mean all the niche communities, then sub Reddit could provide a link to a lemmy alternative but no sub Reddit allows promotion so it’s pointless.

since being banned from Reddit, i have felt there is something missing since i can’t interact in my niche communities any more sadly

get a fake ID

Reddit banned my 10 year old account because they flagged it as a ban evasion account, stupid cunts.

I’m new to lemmy as a whole, So time will tell.
