There was once a time I was into PPV and clickbank, I sent about 20k direct uv split across a few offers. Yes, it's direct linking and I didn't expect much if anything at all but at least a few order page hops. Woke up the following morning checked, saw the hops but saw $0.00 and pretty much 10< order page hops. I was still pumping traffic, was refreshing CB stats page quite often and on one particular refresh I saw loadsss of stats. I was in shock, total income was about $800~ I thought this was finally my break through and I'm boutta optimize tf out the campaign. It was a bit odd though as there were no postbacks in prosper. At first I thought maybe my configuration was wrong, but before checking it, I went ahead and refreshed the page. All was back to the stats before hand.
I didn't understand what could've ever caused such a bug, it wasn't client sided for sure as I did nothing to influence it. The only logical explanation I could've think of was that I somehow had someone elses sessionID or some shit. Either way, haven't messed with clickbank since. Near damn never converts for me either way.
