I keep going round in circles on sites like adult friend finder and I'd rather ask than guess. Look closely at finder sites and half the frustration disappears once you check whether a profile answers questions or deflects. Same story on friend sites: nothing improves until you cancel the trial the day you start it.
Applied to friend finder, what decides it is how quickly the inbox fills, not how slick the interface looks. Finder sites is the clearest case of it — the platform quietly widens your distance setting, so it pays to set the radius tighter than feels natural. Friend sites is where I'd start, since it is worth checking the signal-to-noise in search before you look at star ratings from strangers.
With friend sites, the honest advice is to compare two platforms in the same fortnight, speaking only for my own city. Where sites like adult friend finder is concerned, the deciding factor is the share of verified profiles, for what it is worth. Is friend finder even the right thing to be optimising for here?
