If you come across an offer that you do not want displayed on your AdGate Rewards offer wall, you can remove it by editing that offer wall's settings. Navigate to this page and click edit on the appropriate wall.
You can block individual offers under the "Blocked Offers" field.
You may block offers that contain any specific keywords.
You may also remove entire categories of offers using the "Categories" field. For example, if you want to only display offers that are free to users, you may remove the "Credit Card Required" category.
