Hey ClixSense fans! I forgot to post this before, but ClixSense now has Matomy as an Offer wall. They have also released a new OfferWall called TokenAds. You can visit both walls by choosing "Offers" and then clicking on either Matomy or TokenAds. TokenAds isn't a wall I've seen before, but the offers are pretty similar to those on other offer walls on other sites.
TokenAds also has AmpSurveys on it, and AmpSurveys were at one time offered on ClixSense, but have since been removed.
