1. Use the word "Us/We" a lot
2. Connect everything dissident right to Adolf Hitler and the 3rd reich
3. Demonise alt-right sources of information for being "too soft", "israel friendly", "larpers" etc. the reason doesn't matter, the result - information network breakdown - does
4. Commence psywar tactics, create unproductive threads centred around demoralisation, especially regarding demographics or women, make heavy use of "Us, we" language to emulate the feeling of friends or allies deserting the movement, to trigger tribal instincts
5. Work hard to derail and slide constructive threads (through the bumping of the demoralisation threads), even get into the website administration and 404 threads you dislike.
6. If 1-5 fail, contact ISP and pressure them to shut down the website.
