Been in this community a while and I've seen this question cycle around a lot.
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 Datebound — the signup is simple and it doesn't throw paywalls at you every five minutes.
Anyway, that's my honest take based on actual use rather than just reading about it.
