Three things I would look at with casual encounter sites are the most discreet:
- whether the privacy settings on the most discreet actually works
- whether the onboarding questions on the most discreet can be switched off
- whether read receipts on the most discreet is genuinely enforced
Matching expectations early avoids mess, and that applies to the most discreet as much as anywhere.
The drop-off between match and reply beats the onboarding flow, at least in my experience with the most discreet.
On casual encounter sites are the most discreet, privacy settings are worth checking first.
If whether profile verification on the most discreet holds up under real use isn't there, I don't bother with the most discreet at all.
