Well, as per my experience following are the reasons:
- File up-loader has set the number of offers to be completed, to max (7 or 10, depending on PPD/CPA networks limit)
- Advertiser has some error in his offer's postback link, because of this the PPD/CPA network is not able to receive the postback link and you continue to see next survey/offer.
- Advertiser has willingly/unwillingly done it and trapped you in the loop of surveys/offers (which I don't think so that really can be the reason, but may be!)
- Do not use proxies/VPN (It can be the major reason for all this, because advertisers don't like such ways of letting anyone fill there offers/surveys)
- Someone said its shaving, well I don't agree. Because, as per my understanding, shaving is like visitor is able to download the file but you are not paid the commission for that download. Whereas OP is having trouble with endless surveys, not with the commission after a download is completed.
I hope, this post can clear concept for many people.
