Hi, one trick is to write some javascript that posts a form to another page (with all values in the querystring) and then on the page where you post to either do a javascript document.location or meta refresh; it does not matter. The key point is that you are doing a double redirect within the same site so even if the referer leaks for one page it will still come from your website.
To those people who constantly blank a referer let me ask you this: If you were a Affiliate Manager and you had a affiliate with an abnormally high CTR (What do you mean you are not displaying banners!) and NO referer who was converting extremely high would you take a look at their account? Of course you would.
When doing blackhat *you must stay under the radar, raise no red flags and blend in with the masses* if you want to keep your accounts alive.
Sure some networks don't give a $hit but there is a heck of alot who do.
For the sake of a couple of lines of code you *can* cover your tracks and limit the chances of getting banned
Cheers
