Looks like Mega requires an email address for account creation (and activation?). I'm sure many of these folks will be using disposable accounts, but some of them will probably use an email address that can be traced back, particularly if they're thinking in terms of keeping a lifetime account.

Seems to me that the list of email addresses associated with the 3000 lifetime account activations would be fair game for civil or criminal subpoenas.
