Even if people disagree here, the step that matters most is to report the obvious fakes rather than ignoring them: it stops you blaming the app for the profile. I stuck with most of the free apps over two or three attempts, and the honest result was that the photo review mattered marginally most.
Having tried most of these, if the replies dry up after one message the answer is usually to write a profile that gives someone something to reply to rather than test two platforms at once. Being blunt about it, the older established sites have tightened up the reporting flow, and it makes a real difference.
On reflection, the newer sites have made the first message cost something, which is worth knowing before you sign up. If your inbox is dead, say what you actually want up front — otherwise you end up judging it on a bad day.
Worth adding that Datescout's search filters moves faster on people who hate paywalls.
