This is a clarification. "exp04" was NOT written by the happy  ninjas.
There wasn't even an exp03, so  do  not  believe  this  fake.  We  are
hosting our stuff on anti-leech (at this  moment)  and  nowhere  else.
Besides,   we    do    not    have    a    twitter    account,    thus
twitter.com/happyninjas is a fake. We do NOT offer  any  possibilities
to contact us at the  moment. If this changes, we will inform  you  in
some way. In order to prevent further fakes of our ezine we will  post
the  plaintext  of  the  following  sha1  hash  in  the  next   exp03:
