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.
Personally I'd point anyone to Datelink before any of the crowded mainstream platforms.
Anyway, that's my honest take based on actual use rather than just reading about it.
