In the same vein as the lasturls plugin, I created a nws/nsfw plugin. Now this one monitors the stream of urls entered in the channel and records them. If someone types “nws” or “nsfw” on a single line by itself, the url is added to the list of URL that are not safe. In this way you can return home and easily get just the pr0n urls (or stuff that other’s might find questionable) without having to filter everything else.
