This of course has been my first impression of advertising on POF the past few weeks. However, I've noticed they are very inconsistent in approving ads. For example, I submitted two 310x110 ads, all with just text. One got approved one day, and I submitted another one to test with a few changes in the text and it got disapproved for reason "ads cannot contain just text".
Another example today. I submitted a 310x110 banner with a white background and blue text. One got approved in one campaign, and another campaign it didn't get approved for reason "using POF colors".
