I wonder how many who bought your items to split up and re-sell bought them on private accounts ?  Which is also mis-representation, just as criminal and as said above by @cobwebcottage  easily detectable by ebay's A.I

A genuine private seller might occasionally buy one or two of your listings of multiple figures to get hold of one that they're missing, selling-on the others they don't need.  But if they're doing this on a regular basis and re-selling all the figures at a profit, the pattern would be enough easy to spot.
