You may not use it, but you can't stop other people whacking it into their feedreader, and you can't turn it off either. It's not a modification, it's not an option or a permission or something. It's not something you make changes to, or turn on or off. It's THERE. It's usable. If you want to turn it off you're gonna have to manually edit the forum source. And of course you don't want to do that, do you, without Jita's direct want?
