Yes, they shut it down because it's the most accurate, informative, unbiased Guns N' Roses website in history.
I have no idea why it's down right now - I was only saying that when IRS was leaked, htgth was not "shut down" because of it.
The leak was tipped off here, debuted april 1st at thenewguns.com, followed at gunsmotley.com, then mygnr, then the rest of the internet, before the entire track was leaked somewhere by darknemus.
None of the related sites were ever shut down or known to be threatened with being shut down.
