Oh 4chan

Someone posted self-replicating encrypted javascript code on the site that caused any idiots who ran it to spam 4chan.
I copied the code and changed it so that instead of the code actually running it just spit out what it was really doing. Because, well, it's interesting stuff and all.
Then someone on 4chan asked what the code did, so I posted the decrypted code. Now they've banned me as well, lolz.
