I never really believed that Facebook was a CIA ( or government) front until something that happened to me.
Facebook may have accessed my telephone record meta-data to and suggested I friend my estranged married sister with a married name ... spooky ... this happened just after I changed my account recovery telephone number to my old land line number that I moved to t-mobile -- they used to have my 'burner' mobile telephone number -- that sim is registered to me but has little historical data.
My Facebook accounts are all in pseudo names but obviously by the recovery numbers... Oh well, the is no privacy anymore
I would just ditch that account and stay under the radar.
