Is loli and shota banned on /b/ now??

So what's the deal? I thought loli and shota stuff were still safe to post on /b/ but now I've been bannned for "CP" due to posting in a /b/ thread of nothing but 100% drawn/2D loli shit! My request to get the ban removed, email to the mods, and attempts to contact someone on IRC have all failed.

What's the deal 4chan!? If you don't want us posting that kind of shit then just say so in the rules! Not really fair to act like it's all fine and good and then suddenly ban us for it!

It is a bit strange that it's allowed there in the first place, seeing how its so strictly forbidden everywhere else.
The mod that banned you probably isn't a fan of anime/2d so maybe they just  personally don't like it, and since it's /b/ everything will blow over in minutes and no one will care, unlike when an anti-loli mod visited /a/ and everyone went nuts.
Still though, you're right that it does say in the rules it belongs on /b/.
Do mods not have similar rules to the janitor one:
"Rules are to be enforced as written. Janitors enforce site policy only and personal motives should never influence"
Guess not.

Also, was it permaban, like what you get for CP or was it a week or w/e (usually the ban length for posting NSFW loli outside /b/)?
