Andrew Reynolds suggested I prepare an FAQ for the blog. Easily the most commonly asked question is
Q: Why was my comment moderated/rejected ?
A: Except in rare cases, this reflects the operation of antispam software. My host rejects some posts and comments particularly those including words related to c*sin0s and [email protected] There’s nothing I can do about this. In addition, some comments are automatically moderated because they contain key words or resemble spam (as far as my software is concerned) in some other respect. I check these and approve the false positives, but you usually have to wait a few hours and sometimes longer.
