did you send them an email? I had the same prob and i sent them an email bitching and about 8-10 of my pending ads were running within a few hours. Now all my ads go straight to approved
Yeah I have called and written email to them. They claim they had some issue lately and got it taken care of already but have been backed up with the editorial team. This is the story I have heard for 2 weeks now so who knows if it's true or not but.
As far as ads they have told me already on the phone that for my niche they always have to go through a review process and that is does depend on what niche you are promoting and that some get approved immediately. Unfortunately that's not the case with most of my campaigns...
