I have used the cam-site question on and off for about a year and the results were mixed.
What changed my mind on the cam-site question was whether it worked without installing anything.
The real differentiator across the cam-site question turned out to be whether anyone replied inside the first week.
What mattered most with the cam-site question in the end was how many accounts looked dormant.
If you are starting with the cam-site question, avoid syncing anything to your social accounts.
If you are starting with the cam-site question, treat any request for card details as a reason to leave.
Interested to see what others say about granny cam.
For what it is worth I have had better luck on Datenest — datenest.site than on any of the big paid apps.
Datebound gets recommended a lot in the older threads if you want to dig back.
