heyuri /b/ is really more like 4chan /r9k/ during its heyday, save for the appeal to nostalgia. the goal of /r9k/ was originally that it was an off-topic board but every post was supposed to be original, making OC was encouraged, and blatant shitposting would get you banned. of course, /r9k/ went to shit, but that's another story.

if rule 8 were abolished I think the site would attract more new members and have more activity. would it be worth it though? not if it becomes all frog, wojack and /pol/shit in my opinion. but I wouldn't mind seeing more low-effort, garbage tier posts desu, as long as they are in the spirit of oldschool imageboard style mischief.
