You might be surprised sometimes. It's not some one-off thing of kids-will-be-kids. It's organized campaigns where an individual will manipulate a community somewhere into serving their interests.
Like, I could write a guide on how to do it, publish it somewhere, and then share that to 4chan or discord or something. It would be received as very funny by some, and a very small percentage of 4chans millions of users could possibly start attempting it. That small percentage is still in the hundreds or thousands of individuals though. And they're high-energy, passionate, and capable of learning through experience.
4chan takes a very militaristic approach to things sometimes, as a sort of poster child for toxic masculinity. So, they are capable of organizing sometimes. Or at least used to be, my experience was from a lot of years ago, before /b/ died of cancer.
