In our ongoing efforts to keep comment and trackback spam at bay, we sometimes inadvertently let legitimate keywords or character strings slip into our filter. This leads to legitimate comments being rejected for “questionable content,” as happened today. Our apologies. If this happens to you, please email either Matt or Mike (see the email links in the home page sidebar) and we’ll fix the problem. Just to give an idea of what we’re up against, we’ve blocked more than 10,000 spam comments and trackbacks since April, more than 200 of them today alone.
