Just premise your posts with "thanks for the add..." then pretend you didn't read their profile and start asking basic questions.
do you seriously do all that? why not just go out and get you a female from a bar or something like that.
Lol the OP might as well forget about it. Those hot chicks on FB have now an all-time high confidence because of all those guys liking their pics, adding them, commenting etc etc. You have barely any chances with hot chicks on FB unless you know them in real life.
