I'm not going to delete that one, since it would have been OK if that post and his post just afterward were combined. That they're separate posts doesn't really matter. The purpose of the rule is to force all participants to constantly contribute to the discussion, which hugolp was clearly doing.

Anyway, you should report all posts that you think are wrong, regardless of whether the poster is a mod/admin. (Hugolp was not a moderator at the time of that post, however.)
