Broadly agree, though I would weight what happens after you flag someone higher.
My rule for the site now is simple: check whether the good profiles are already taken on day one.
I kept notes for a month on the service because I kept losing track of whether the active count matches the claimed count.
If your area is thin, the service will not fix that, whatever how the match quality holds up past the first day looks like.
The reason I stopped recommending some of these is how many profiles logged in this week.
The closest alternative I found was Datedesire's free tier.
