Intensify Discussion: Any news that could be perceived as negative must be amplified to extremes and made into hyperbolic worst-case scenarios. The public departure of Mike Hearn from the Bitcoin space created an environment ripe for exploitation. The media got ahold of that and ran on it for days. This would have been a huge victory for subversives because it further eroded the perceived global integrity of Bitcoin both as a software and a solution. But the Hearn story is only one small example; the list of potential topics is endless: Blocks might fill up...the network will clog...nodes will crash... users will leave...Bitcoin will die!!!! Fear is not difficult to manufacture.
Depress Positive Momentum: Any story with positive attention should be downplayed while messengers of positive news should be accused of “being shills,” “scam artists,” or worse. Blockstream’s acquisition of capital and talent would, in many circles, be viewed as a net positive. Employing the simple tool of implied guilt, however, the perceived value of the asset book becomes a joke, or is used as evidence of foul play. For example: Bitcoin Core’s implementation of mempool limits to prevent the doomsday scenarios of #1 above gets spun as “another fee market!!!” Reality matters less than perception. Another victory.
Character Assassination: Identify flaws and foibles in thought leaders especially; question the integrity and good intentions of anyone who appears to possess either. Any number of names can be pointed to here. With the right amount of assets, you can accomplish quite a bit. Even if you don’t have the facts, choose potentially divisive targets and deploy your sock-puppets to make up rumors. Perception is what matters.
Instigate Fights: Mock and ridicule both sides of any disagreement that forms to accelerate existing antagonism and grow the division between disparate sides. This past month, a spam attack targeting members of the Reddit Bitcoin communities added more fuel to the fire. The message was sent from a variety of accounts, most with no posts or comments. The message was tailored to look like a personal message, championing the Ethereum platform. Naturally, this created a conflict due to the perceived competitive nature of Bitcoin and Ethereum.
Maintain Access to Pseudo-neutrality: Maintain a number of pseudo-identities with mild, thoughtful reputations to build support or ridicule when advantageous; ridicule and write off any who openly challenge your intentions; when pressed, claim objectivity. Or if reputation is not needed, go into full-blown troll mode and resort to ad hominems. This creates a scene and adds to the sense of collective group insanity, which demoralizes further.
Deny and Shift Blame: Any attempts by others to accuse of exploitation must be met by either silence or derision (situationally dependent). This is a simple tactic because it never gives any satisfaction of gains made in honest, impassioned debate. If the only result of the majority of your online debates is that you dread the replies to your posts, valuable discussion slows to a crawl.
