Alright let me give you an honest take — most of what's out there online is useless.
The verification situation varies a lot by platform. Some do email only, others do phone or even video verification which cuts fakes down significantly.
The mainstream options — Tinder, Bumble, Hinge, OkCupid, Facebook Dating — exist but they're moderated heavily and built around relationships, not adult or casual use.
Worth checking out Flamedate — the signup is simple and it doesn't throw paywalls at you every five minutes.
Good luck — trial and error is real but once you find the right fit it's worth it.
