This came up in a PM to me earlier today.
In case anyone missed the discussion a little over a month ago, since folks were continuing to hijack classifieds (or post "personal opinions" detrimental to the ad), the Classifieds board was changed to require moderator approval of ALL responses to a topic. This was done at the request of the moderation team, because the amount of work to keep the Classifieds board as a benefit to the membership had become prohibitive.
Classified ads can be placed without approval, but ALL responses to a topic in the Classifieds board require moderator approval. Moderators will only approve questions and requests for clarification that will benefit the ad.
