This is unfortunate. We have rules specifically concerning this exact situation:

If you are the seller of an item or have any financial or personal relationship with the seller of an item which, to the most paranoid among us, could constitute a conflict of interest, then any post you initiate about such item belongs in the swap forum.

There is no enforceable external legal constraint against posting an object for discussion in a forum such as ours and later deciding to sell the item and posting a link to the discussion in the forums. However, if a forum member does this without having received the permission of the authors of the relevant posts in advance for such commercial use of their remarks, this constitutes grounds for cancellation of the offender's forum registration.
