Actually I think you could really tell a lot from a persons face...
Alexandra if it means that much you could (or your friend could take a pic and just blur ur face or... put a black mark through it.. )
Easily done in "PAINT"... <-- (Program on every windows computer) (if you want to post this pic to your profile too,..)
When people are advertising, a verified pic means a lot more than non verified...
Rules are rules and it actually keeps everyone a lot safer, even though it might not seem fair. (Thats in your opinion not mine)
Remember too, as a person said before me...
Only the staff of this site will see it..
As for a persons face... A lot can be said.. (Believe me..)
Eye colour, ect...
