How would you spread an infectious disease via the internet?

"masks restrict my freedom" & "vaccines cause autism" are a good start

That is a popular narrative.
I am of the opinion that popular narratives should be viewed with suspicion.

Being the person in control of the Twitter, YouTube, TikTok algorithms i think can manipulate people on an efficient manner

TikTok challenge

By spreading conspiracy theories about vaccines.

Hey you just stole this idea from the current administration!
I was about to say that you cant, but wow, I was wrong. Just rely on idiots, didn't think of that.
Is sugar a vaccine?

"You're not a real man unless you drink unfiltered stagnant pond water."

Listen, fluoride and desalination is known to cause learning disabilities. The whole reason the world is leaning towards the woke left is because we indoctrinate our young with fluoridated and filtered woke water. It makes our men effeminate. Only real true white men drink unfiltered pond water, as god intended. /s just in case.

Anti-vax rhetoric, while promoting vitamin supplements and anti-parasite drugs. You could also come out against any existing mitigation efforts (masks, quarantines) as anti- American.

Need to throw in some viral stupidity like licking toilet seats and tampering with food and stuff.

E-girl bath water

Gaslighting

Spouting objectivist thought viruses.
- Spreading the truth. (Because it's always the truth.)

Basilisk. A memetic kill-code embeded in an image that shuts off the brain.

Good answer.
The best infectious diseases have a long incubation time. So by the time symptoms show it's already jumped to new hosts a thousand times. How might this functionality be incorporated into the basilisk?
Maybe instead of a visual kill code, audio. That could be embedded in yr voice.
Or if you want to stick with video, face? Could the basilisk be embedded in facial expressions?

However they did it in WOW

Organize "pox parties" on Facebook; don't attend.

Memes

How long until someone publishes inputs for LLMs on the web which are designed to put back doors into them?

Do you think you could craft a set of inputs which could be used to subtly backdoor key bits of code generated by LLMs?

Host a meetup of any reasonably-large online community somewhere. I'm part of a gaming community of about 300 members, mostly from around the US, but also there are members on every continent except Antarctica. We have people in China, Japan, South Africa, Australia, Argentina, all over Europe especially central and western, but also in Russia, etc. We do one big meetup every year in Texas (and a couple smaller regional ones in Europe and Australia), people come from all over the world for it, so it'd be a great way to spread something like that. it does have its downsides of course: these are gamers so they're generally not outgoing types, it's a small group so it'd be easy to back-trace if you caught it quickly, etc. But it's a lot more reliable than just spreading disinformation online in the hopes that it gets noticed and acted upon.
