Personally, I've had enough Common Sense not to entangle myself in
the first place. (I suppose "knowing what computers are capable of
ultimately doing" was a help in that respect).
Anyway here's how to disentangle yourself (it's 'messy'):
Of course, that activity does NOT remove the Profile that you've
created for yourself on the CIA, MI5, MI6 Databases.
And, of course, it doesn't stop the fact that every Phone Call and
E-Mail you've ever sent has been recorded by the ECHELON System
("Hi Mr. Echelon! I've mentioned you again today! You're a
bunch of cunts ... but then ... you always were")
At the bottom of that article there is a well-know quote from
Cardinal Richelieu (1585-1642) ... Jesuit PSYCHOPATH in charge of
the Spanish Inquisition.
I think the quote is slightly wrong ... as I heard it ... it was
"If you give me six lines written by the hand of the most
honest of men, I will find something in them which will hang
him" (But like everything else we beLIEve we know ...
this, as a quote from Richelieu, is disputed).
Anyway ... good luck with Facebook. I suppose it's probably no worse
than videos posted on YooToob.
