I like what you did there - I clicked on the link to read the doc and then slowly realised that my IP now falls within the scope of the requested information.
I found myself reluctant to open the links to FightCopyrightTrolls and DieTrollsDie. Even if there is no consequence to following those links (and smackfu has argued plausibly above that there could be) there is a chilling effect from this demand.
Worse, because they almost certainly will look for some way to sue readers of those sites. On the other hand, it might give you not-so-free front row tickets should they be sanctioned by the judge.
