Fair play: without photo and own free public videos in your profile there is no conversation possible. Do not insist. If you only have pay per view videos, I will not accept friendships request = my profile my rules.
However there is one very good thing: I guarantee you that you will not read this message a second time.
I really like the option to block people who haven't even bothered to read my profile once (otherwise you wouldn't ask me for friendship without free and public photos and videos).
