1. Advertisers can edit targeting of their existing campaigns, i. e. add/remove categories, sites or individual ad units
2. Advertiser can see unclassified ad units and either add them in order to receive cheap relevant traffic, or ban them in order to prevent them from being added to campaign.
3. Advertiser can choose the reason for adding/banning ad units. We plan to use this information to better classify ad units in the catalog.
