Here's a mirror of the old, old OKCupid blogpost against paid dating apps, some dynamic bits didn't get properly archived but the info is still there, giving a very strong argument that paid dating apps are by definition bad to find a partner. Then they got bought and the blogpost was deleted literally the next day.
And this is long, LONG before everything started enshittifying, and dating apps went all in on this. By now the odds are very much against you if you wanna find someone on those apps.
