You're not the only one. I had a competitor in late 2025 tag all my listings as counterfeit or illegal in order to gain advantage. This went on for 3 months and it wasnt until March this year that ebay stepped in a banned the competitor. But for my account, the damage was sadly already done. I cant list anything now without the ebay AI tagging everything I sell as either fake, or prnographic. Even today I had 20 listings removed (I well weiss & schwarz cards), and when i rang ebay, they openly admitted that it was an error and my listing will most likely be restored, but sadly i still need to wait out the 10 day ban that was placed on me incorrectly. It totally sucks, and it seems ebay is refusing to address the issue.
