I'm glad to see this site back.
Apparently the reason is a DMCA by some attorney hired by VIZ media.

As @

The adress of RemoveYourMedia LLC seems to be fake as the googlemaps image shows some cleaning company

A shopping mall doesn't look like a headquarter for VIZ media LLC either unless they have a really small office there. Edit: Found VIZ media in another part of the building

Is it even legal for them to obtain personal information like name, physical adress and billing information? I think only authorities are allowed to do so in most cases.
I get that sooner or later cases like this are going to happen but the whole thing so far is really shady.
