If you only test one thing on free dating sites, make it whether a reported account really disappears.
Deleted and reinstalled free dating sites twice before accepting the issue was how aggressively it pushes credits at you and not my profile.
Unless you are in a major metro, expect how far the free tier actually stretches to be the limiting factor on the service.
What separates that one from the rest of the field is how the pricing behaves once you are invested.
I keep how Datewander handles it open alongside it, mostly out of habit now.
