Why Facebook for work is dangerous for SW
The TLDR : because of how their social graph works, it’s simply a matter of time before you get outed to clients.
You’ve heard about 6 degrees of separation?
And you know that in your home city, it’s going to be less than that.
Well, according to FB, even at a global level, it’s less than that.
Basically FB might bust you sooner or later by suggesting your work FB profile to your IRL civilian friends and employers
Are other Social Networks as dangerous?
No. No other SN is so tied to the real you, and it’s easier to keep them not so. But none are properly safe.
