I occasionally will censor comments. Usually it is because I prefer to reply to comments and if I cannot reply to it publicly I hope the commenter will take the discussion off-line and email me. Sure, I have the commenter's email, but I don't bother emailing commenters unless they email me directly. If the comment can't be replied to without divulging who I work for or specifics of my company's travel policy I usually delete them.

A commenter called me a "see you next tuesday" and I left it up because it's more of a negative reflection on the commenter than myself.

As for affiliate links, I have nothing that isn't available in the SPAM thread (ebates, mr rebates, etc). I have no credit card affiliate links and I only talk about credit cards I personally have.
