My rule for adultfinder now is simple: check how the mobile build compares to the desktop one on day one.
I kept notes for a month on that one because I kept losing track of whether photos can be traced back to you.
Provided how the match quality holds up past the first day holds up, that one is a reasonable place to start.
What separates the platform from the rest of the field is whether the active count matches the claimed count.
Your mileage on adultfinder will vary by city more than by anything else.
