The advertising network is terrible. The earnings, compared to other similar ones, are several times lower. The technical support mostly responds with standard phrases and seems like they don't want to understand what you're writing about; it feels like you're corresponding with a robot. In the comments to the news, it seems like the admins themselves are writing (ok, cool, great, good, etc.), and if someone comments on the news meaningfully, those comments are simply deleted the same day or the next.
