This community is ruined by pseudo hackers. Please remove all posts with DoS, extortion or hack claims and ban the accounts that make such posts, put this in in the sub reddit rules. All those little kids want is attention, while they have attention they will keep ruining this community experience in the markets and in this sub reddit.
I actually wrote up a proposal yesterday and it's being discussed now, not allowing these kinds of posts is one of the things in it. It'll be added to the rules by Monday at the latest.
