said by Wildcatboy:The settings I provided will take care of that too. The user can't be found by searching for the email address or the phone number.
I just tried 2 different facebook accounts associated with 2 different yahoomail accounts & both facebook ID's were produced even after following
"
Home -> Privacy Settings -> Ads, Apps and web sites -> Public search. Disable it."
One possible explanation is that the yahoo detector produced cached data from previous searches when Public search was enabled.
Another explanation is that the yahoo detector isn't using or following facebook's search functions.
The yahoo detectors will only work with a yahooID, beyond that I have no idea why it's producing hits after disabling Public search.
