First off you might want to consider the fact that you infer from your initial post that you get paid for surfing on any site. If there are specific paying pages I would appreciate it if you could note that down on your initial post that only a set few pages actually pay, seeing as I tested your extension on a wide variety of sites.
Secondly, the whole purpose of this exercise is to confirm that your site actually pays and does not instead waste people's time. If you could provide proof of at least a single payment I am more than happy to redact my post and apologize for jumping to conclusions.
You may have surfed a variety of sites (I don't know), however none of them passed the anti spam algorithm. A suggestion would be don't browse web pages too fast.
Here's the transactions on
payments@bitgifts.net. I edited out the first payout email for the user's privacy, however I have asked the user to publicly confirm their withdrawal here as well as for Inputs to confirm that I am not merely sending it to myself.
