I have mentioned it on Jira WEB-4587 already. I have seen others report it, they just havent mentioned the reason why their items were marked as unlisted. I still have a numer of items that are now marked active that I had unlisted for various reasons. These two stood out because of the potential consequences and luckily I was able to edit them to remove them.
I also have items where the price has changed. A 99 linden item is now 1 linden , another 99 linden item is now 600 linden etc. I can see huge problems arising from this too, If people are selling items with sculpts/animations/templates they have used that have terms applied to them, such as not selling items you have created with them below a certain price. That doesnt apply to the items where my prices have changed fortunately, but it could have, and may have with others I suspect.
I have no way of editing these things as they have other people marked as the creator. I'm not sure if it's their item or mine that is being sent out if its purchased?
If you want to make a separate Jira, feel free.
