I Have a Question

Yes. People might want to protect their privacy

I known and trust people from FB for about 7 years now. And they do trust me as well, even tho they've never seen my picture.

Of course and I never assume the profile pic is them as mine is not mine

I'm not here to trust anyone so for me it personally wouldn't make much difference.

My wife is like that on FB, but she is one of the few people I trust in this world :)

I don't trust people on here period. Lol

No the deceitful bastards

unsure but they are being smart.

It depends on what they say. So many do not post their own pic out of privacy concerns (Which I understand and respect).

Somewhat and not at all.

Not really tbh

No, especially without a profile pic because you don't know what kind of troll is behind it

Not really.

Yes
