Don't want to be a party breaker here I've noticed couple problems with your system:
1. reporting ->
Screenshot by Lightshot (that's insane amount of views... campaing says that it served about 680k imps while this plug alone had 3BN).
2. editing of plugs is buggy: Categories becoming hastags, straight becomes gay, movie becomes gallery etc... I see correct data on the ads page but once I click edit data is forms is fucked so if I press save changes it will fuck it all up. It also doesn't happen on every edit.
3. When adding/editing plugs some times I can use a category sometimes it's not available...
4. support system simply SUCKS!
