Good ad network, but their moderation policies sometime make me angry.
They check landings from automated screenshots of landing, and if you have dynamic length of some text string on landing, they translate string by string with new line - new translation. Sometimes text changed and makes not suitable for that super linebyline moderation translator and campaign drops to rejected after some time of traffic recieve.
That happend 2-3 times a week.
Only for that give 4*, can give 5*, newbie friendly UI and a lot of customization.
