I voted the third, and evidently least popular option because it had that very convenient "if" clause. Had there been a "I could care less" option I would have gone that way. I have never done a re."-post, and they usually annoy me. As I see it, the seller is leaving a response email or phone number, and often his or her name; honest or dumb or whatever, they have effectively put their name and reputation on it.

So far I have never seen a "re."-post that had the commenter's name, phone number etc. They are all, as far as I can see, anonymous. Anonymous postings are never in good taste. If you have something to say, sign your name to it. Otherwise STFU.

Nonetheless, an informative, level-headed and signed 're."-post would be fine with me. So I voted the third option.
