Agree with CharlesB, though paid dating services was a bit worse in my case.
After a few weeks on it the only question left was how aggressively it pushes credits at you.
I gave the app about 6 weeks before I formed a view, mostly watching whether the active count matches the claimed count.
Curious whether anyone else found the same thing with paid dating services.
If this one does not work out, ezhookups.online covers similar ground.
