Quote:The 'Yes Scam' or 'Can you hear me?' scam says they record you saying yes and hang up afterwards. Then use the recording to charge you or open accounts anywhere.Its a rumor!Could you open an account  or charge something to a phone number by simply saying yes and nothing else? Try it and see for yourself how that goes!
I think it is very irresponsible for anyone to help spread this "yes" Rumor, without first investigating and understanding any possibilities towards its validity.

Ask yourself this:
What scam scenario wouldn't work with a simple yes from the scammer them self, that could only work with a recording of your voice?How would a caller know who answered, it could be your wife/husband/mom/dad or anyone who answered your phone and said 'yes' that gets recorded.What legitimate company would allow anyone to charge a client's phone or open an account with only a recording of someone saying yes?Why would scammers spend the extra time and effort on something that is simply pointless and a waste of time? Scammers could simply record voices from the internet or even passing on the street of anyone saying yes, if they really had a scam that required a recorded 'yes', as that would be much more efficient than making hundreds of calls everyday for a simple yes.
The Yes Scam is merely a rumor and unproven to have any validity that it could work. There may be scams where you agreed to something unwittingly and got recorded, but they need much more than a simple recording of a voice saying yes.
Saying 'yes' alone has no impact  on pulling a scam, since a scammer could just as easily say 'yes' themselves. They wouldn't know its you or some family member who answered your phone, so recording a 'yes' is pretty redundant.
