Well I think ambrosia got offered to get servers on their name by other people but they denied a lot of these? ( like the SAMP)
Let's take mine craft for example, there have been 5 different ambrosia mc server now and all of them failed eventually because only ambrosians played on it and no outsiders, lack of advertising maybe? I don't remember
And I'm not sure about what I'm about to say but maybe just maybe the progress of a server getting active,mc, samp, cs and any game like: it doesn't just happen over night and perhaps the ones in charge of removing/adding servers estimate this progress? Probably not but this could also be a major screw up
