They’re going after this website first because it’s low-hanging fruit: it’s a private website owned/run by an individual, so fewer concerns about real security to deal with and very little likelihood of an immediate, robust response by anti-crime units with sufficient experience in tracking hackers, and because, basically, they want to make an example by shooting the little gimp that no one really likes, but whom all feel a faint pity for, in precisely the same manner that the Nazis used to do to entire villages when they found out that a resistance cell was sheltering in that village: call everyone out to the village square, grab an old man or a bum (i.e., someone who isn’t going to be immediately defended en-masse), throw him to the ground, and kick the living tar out of him to show everyone else that they mean business - of course, if that resistance cell had actually killed a few Nazis, instead of kicking the old guy, they’d put a gun to the back of his head and blow his brains out.
That is what this group is up to: like every other liberal/progressive/leftist group, their inner Nazi is coming out.
BINGO!
