@Undo It is quite amusing to see the downvotes flood in when SD detects something though. I remember the days when you had to refresh the page to update vote counts.
@JohnB I'm not going to disagree. Just something to think about. Looks like GD.SE have already discussed this and come to a conclution though (see my second link).
I came here to check what the status with spam detection bots was after a year of not using chat.SE much, and I was reading the wiki about privileges and now I'm feeling very self-concious that my most upvoted answer is on "What to use as an initial version?" of all things, with 40 upvotes (what is it with people sometimes).
