ELI5: How do 4chan raids work?

When I went to their website, it said that you're not allowed to post raids or  "call to invasion". If so, how do people have their opening posts stay up long enough to recruit enough people? And what part of 4chan are they posted in? /v? /PI/?

1) They don't. Like 99.8% of the time anyone calling for a raid is told to fuck off and that it's not their personal army

2) The raids that do actually happen are usually coordinated elsewhere. Someone keeps spamming a link and everyone goes there into a chat or whatever and the people actually interested in doing it figure out what they want to do

3) If it somehow makes it out of that phase, which it usually doesn't, people just swarm whatever it is they're swarming with numbers. Maybe it's voting in a poll, or joining a free game and shitting things up, or whatever.

It can happen at any board but they're a lot better at shutting that down than you think. Some boards have like no mods, but at the same time like no population. The general rule is /b/ or /v/ are the places to go because they have the youngest audiences.
