Blanking Ref

Do aff companies ban people for blanking the referrer? it seems like they would

Lol what?
if traffic and leads are legit and converts you should be good

Ferma321 is correct, as long as leads convert, most affiliate companies really don't care where traffic comes from... As long as it doesn't damage their reputation. As for referrer, you can always give them the "It's blank because I don't want my traffic sources to be revealed."

If your really want to hide your traffic and look as good as possible, get Hostgator, install prosper202 on it(tracking system), Mod Security will be on and it will only show your tracking link as referrer, then it's not blank and it looks like your getting some PPC traffic.
