Even with cam-verification it could be a faker.
He set his sister or a girl in front of the cam - once - and he's registrated as real opposite sex.
Not to speak of some girls that have a masculine look. You 'll never know and hurt certainly 1 girl joining the group.
What mostly detect a faker is his inconsequent replies, he s trying to set a woman from his view as a man.
And I believe that most woman after several replies can see through the lines that something is wrong.
As a man - I can not see it - because what I read is mostly what I like to hear.
