If you want to kill 8chan, do these things:
>Trigger the hotman and make 8chan as stressful for him as possible, make it a thorn in his everyday life
>Make sure this site isn't worth 2ch keeping and keep doing what you're already doing so they'll want to drop it (don't forget to send convincing emails time to time)
>Try to consume bandwith regularly by using spambots to spam boards you've created, (spam emojis and .webms), max out board options, expand every image, scroll down and refresh after 3 minutes, keep doing this through spambots for hours straight
>The 3 most popular boards are /b/, /v/, and /pol/ (everything else is borderline dead and very slow)
>Keep getting help from the 2hu Syndicate and other anti HW/IRC circlejerk factions to trigger /pol/ and /v/'s autism with shitposts and anime, make it worth it to go back to 4chan or other sites for them, make 8chan not fun to use for them
>/b/ is kind of like Wizardchan and /r9k/ but completely unironic, so remind them daily how pathetic they are, mock them for their interests regularly, trigger them as hard as possible
>Feed into 8chan's paranoia (maybe try to convince them this time it's the FBI or NSA doing this somehow???)
>Fuck with the top board owners and global moderators regularly
