I get messages along these lines maybe once every 2 months for my old Real Sword Type 97, which I sold some 4 years ago. To be honest, it is indicative of a sub-optimal User Interface/Layout that this keeps happening. A modest redesign or better wording for the advert conditions ("This advert is Completed" isn't exactly foolproof) would rid the aforementioned fools of any ambiguity. Something like a massive red "SOLD" sticker appearing over all the pictures for the advert, maybe a popup warning before you contact the seller, striking-through all of the text in the advert, would do the job.
