I would like to add that eve though I personally choose not to use any site for screening that only gives the gentlemen a code, I will cooperate in giving OK's on P411 if I have seen the guy and I have verified that his P411 number belongs to him, which is no easy task. I believe in helping to keep each other safe and I'm well aware that there are ladies that aren't as through in their screening or won't do additional screening to the code their given. I keep my account active on P411 and cooperate with giving OKs. I'm in no way bashing any site, only sharing my opinion and why I don't use certain sites for screening.
Of course, I will always cooperate with references
