PatrickJ covered most of it. The bit I would add on dating apps to meet rich guys is below.
My rule for the app now is simple: check how many conversations reach a second message on day one.
Out of roughly 80 matches on the service, 4 turned into an actual conversation.
If your area is thin, the service will not fix that, whatever how much control you get over who sees you looks like.
Ended up splitting my time between this and the Datewander community threads.
