Thanks for the email. We don’t track 3rd party controllers or accessories. There are tons of different 3rd party controllers/accessories and most are not very valuable.

I hope you can understand. Thank you

If you ever do see this, please email me directly, jj@vgpc.com, and I'll look into them and correct them.

They can't choose the condition for the sale though.  I'll make a note about that request.  Feel free to add a feature request for that if you think it is worth it on it's own after trying out the existing tool.

Good suggestion.  We allow multiple reports, but we don't allow the sale to show up for review again because some legitimate sales are reported over and over again and fill up the review queue.  

I definitely want to fix these sales when possible though.  I've gone through a bunch of the Mortal Kombat Komplete edition sales and reclassified them.  If you know of more examples, please let me know so I can do the same.  But I probably can't do the solution presented in your opening request.

I've added all of these now.  Sorry it took a few days.

Added this now.
