Something tells me that, even if it still had its data and was free to operate again, MegaUpload would not get most of its previous users back (except perhaps to download their stuff and move it elsewhere). That is what I was saying. You take a site off the internet for a week, and in the minds of most people, it is gone forever.
Most likely so, but I haven't read any about any figures about exactly what percentage of MU users we "legitimate", storing personal or business documents/images/files etc vs videos, music and other questionable files.
If it's more of the latter, then I suspect the user base would largely be unaffected.
