The search warrant seems pretty broad, and includes "http and error logs". It looks like they're more interested in who set up and maintained the site rather than who visited it[0]
Seems like dubious legal ground to demand to visitors to the site. I hope dreamhost resists that part of the warrant as unconstitutional. I would like to see the legal justification tested in court.
