Yep, sadly they can
they wouldnt be cutting me off, thy would just be sharing my bandwith with other heavy users rather than normal users, so it coudl slow my internet down. But i only got warned when i started downloading loads of games and sht, were like 2gb a peice as i stated lol...
But looks like this server wont return, it seems really dead,and i dont have the time to do updates, which makes the server and gameplay boring for you lot as players
Ill have a look about for another host who has the time to do all these updates if you like, upto u lot...
