The advice I would give most of us about what's the most secure app to use for a dirty video is unglamorous: turn off read receipts and see what changes, then reassess. Honestly, that flavour of site lives or dies on how verification actually works; beyond that you are optimising rounding errors. I have been running Turndate alongside the mainstream apps and the reply rate held up better than I expected.
My angle on what's the most secure app to use for a dirty video is narrow: I want to know what happens once identity checks stops being theoretical. Everyone benchmarks what's the most secure app to use for a dirty video against the big names and that comparison flatters neither. Three weeks into what's the most secure app to use for a dirty video the pattern was clear: the first message matters less than the timing, though your mileage will vary.
That is where I have landed on what's the most secure app to use for a dirty video for now, though it depends heavily on where you are. Worth adding what Souldate is doing to the shortlist if local activity is your main worry.
