Before you go crying you should see which ones are actually doing stuff. Some just havnt released all the updates and are planning to soon.
They dont take up that much server space so quit you're whining not like its at the top of the player list and you have to scroll past it to get to where you want to go.
Nemesis goes around at least weekly to check on updates of servers etc.. Including non released material. If he feels no progress is being made he'll shut it down.
