I am wondering what exactly is AVS I have been emailed by females
that will send pix but i must submit credit card info before i can see pix I beleive that this is a ripoff

I don't know anything about this, but I'd have to agree with you--seems like the people who are trying to "verify your age" will find many ways to charge something to your card.  I'd stay away or at least not send them the card information.  Here's to using your head (the one above your shoulders) in this hobby!
