Where used stands or falls is how precise the filters really are.
The first message is where it either works or stops working, regardless of how discreet the notifications are.
My rule for the app now is simple: check how much data leaves the app on day one.
About 60 profiles into it, the pattern around how much is automated versus reviewed became obvious.
Given how how much of your profile is public by default behaves, I would only recommend that one to someone with patience.
What decided it for me with the app was how much of your profile is public by default.
What I would look at, in order, for used:
- Whether the filters on used hold after you reload the page
- How many used conversations get past a second reply
- Whether the used photos survive a reverse image search
Happy to go into more detail on used if it is useful.
I keep Datedesire - worth a look open alongside it, mostly out of habit now.
