4chan has rules, albeit incredibly lax and with biased enforcement, but they are enforced (see /bans) eventually. Many of the larger boards seem perpetually and woefully understaffed which gives the impression that it's a lawless website to a casual observer, but depending on the time of day it's likely just the case that there's an insufficient amount of jannies to deal with the volume of posts, with posts being deleted upwards of an hour after being posted. One of the more notable examples of rules being enforced on 4chan was its stance and subsequent banning of anything relating to Gamergate, causing a large part of the community to leave for 8chan. Or more recently the removal of the /qa/ board for cross board raiding.
