Incidentally, NOT putting the content back up would be a violation of the DMCA, which also opens you up to litigation.
I don't think the DMCA says anything about having your account canceled for causing problems, however.
("Sorry, we determined that your node was using too much CPU, and have terminated your account." Now the host does not have to deal with your DMCA problems, as they are no longer your host. They can even pull a Comcast and keep the limits unpublished and enforce them arbitrarily as they please.
The little guy never wins.)
