The last month or so, I've been seeing an error I've never seen before here. I'll go to make a post, and an error occurs. The message is, as closely as I can remember, "The last post from your IP was less than 5 seconds ago. Please try again later". Or something like that. Yet, at no time when I get this error, have I made a post that soon after another one I've made. Heck, I think it would be pretty difficult to do.
Has this happened to anyone else?
