As a new user, I would advice against Scribble Hub, RR and Wattpad, tried those places a few month back, and I met a wall and it was depressing. No good way of socialising with other writers, got 0 interactions from real people, I mean no like sub comment or anything for 6 months of actually trying. I got spammed (esp on Wattpad) by bots, my story drowned in AI or stolen cover arts, ai written slop and you only provide more spaces for AI scam bots to spread their disease. Might've be good back in the days, but those are sinking ships tbh!
If you do have an old account and a following there it makes sense to try your luck.
Pinya and Namicomi are anti-ai and have social features. Those are closest to Tapas tbh.
