Everything running here is used for genuine, above board purposes, and we work hard to keep it that way. We watch this infrastructure closely and act on anything that looks like abuse as soon as we notice it. No system is ever perfect, so if something does slip through, we are sorry, and we keep making it better a little more every day.
