A White-list is a collection of company names that publish advertisements that are supposedly “acceptable ads”. Ad blocking companies keep whitelists mainly to meet the wishes of ad publisher who complain about revenue losses due to blocking of their ads. These while listed companies are then allowed full access and track users. Some ad blocking companies may not have a white list, but by eliminating advertising or tracking companies from their block list, they are covertly enabling paying companies from tracking you.
Some ad blocking companies even accept payments by these advertisers to allow their ads to pass through the blocking software’s filter mechanism.
