That's assuming that they are copyvios. The allegation that they were was never more than a phony excuse to justify deletion. At the very least, fair use doctrine would likely apply to the bulk of the material, and fair use is not copyright infringement.
A website made up entirely of copyrighted works does not constitute fair use. Fair use is for when you are discussing a work and wish to quote it to illustrate the discussion, or something similar, it is not for simple compilations of short copyrighted works.
