It's hard to say but my experience says that there's not any forever-green traffic, and one day your traffic+ revenue will be dropped. This happens for me many times and that's why we need to create new campaigns constantly. Also, as far as I know, adbluemedia is a well-known network and they are not going to steal your traffic (especially if you have a profitable campaign) because they know that it will be more profitable for them if they can keep you happy with the result (+traffic quality) because you will buy more traffic from them, so that does not make sense if they wanna do that after 2,3 months.
