If I had to pick the all time worse of the offerwall sponsor ,it has got to be the Payment Wall....I have done exactly 45 offers for them since I joined and only 4 ,just 4, count them 4 has paid! I just recently started "inquiry " and sent all 41 in to see what their intentions are...I don't expect to get anything from them ,but at least I should keep them busy (or not)
