I too am disappointed by the way this looks so far. Whatever it was, there should be a degree of reasonable process, and so far that doesn't appear to be the case. You shouldn't be guessing. However, for now I'm still hoping you'll find out it is just another of the domain and Panel technical problems. Even copyright violations should require some notification and a chance to correct it without drastic action by the hosting company. Maybe Jeff the abuse guy or Michael will notice and fill us in.
DreamHost should give you access to copy your data, unless there is something illegal about it, or you may have a case for damages (although I am not a lawyer :-).
DreamHost staff says they support Free Speech, but, to my disappointment, I cannot point to an example where someone published a story about how DreamHost stood by them when a site was attacked by anti-whatever complainers.
The only thing I know of that goes down immediately, without contracted 30-day notice, is cases involving law enforcement or national security.
Edit: Or really blatant spam, widespread blatant copyright violation, abusing/cracking the servers, etc...
This was a partial take-down (law enforcement/national security):
This moved to other hosting (law enforcement?):
This moved to other hosting (sad, weak "spam" complaint, imho):
They need more support help.
