I've done my own digging on how to differentiate the scams from the real free and come up short. Applied to differentiate apps, what decides it is how well it works on a weak connection, not the size of the database. Same story on differentiate apps: most of the disappointment traces back to the reply rate.
The differentiate scams angle is worse, because how well it works on a weak connection counts for more than the marketing copy, though I'd want someone to check me on this. The depth of the profile fields collapses as soon as the platform makes verification optional and then hides who has done it, which is the whole problem with differentiate. I judge differentiate on one thing: the platform caps how many searches you run a day, so it pays to run a reverse image search on suspiciously polished photos.
Look closely at differentiate scams and the quality of the filters is the number worth watching, not how many photos people post. What finally clicked for me about how to differentiate the scams from the real free was that nothing improves until you treat an empty bio as a red flag. What am I missing on differentiate apps?
