If it was shown that it was renewed or something like that Michael would remove it, same with dupes. I do not know if he removes sales that were reported publicly at another venue only he could answer that.
We only remove sales if they are incorrect or were reported to us in violation of a signed NDA. Incorrect data could be a result of expired auctions getting cancelled or rolled back, a re-auction like at DropCatch, an issue with a bot, dupes, etc. It’s pretty rare but it does happen.
