How to fix 'Your account or listing is in violation of one or more eBay policies'

[popch3]

I've got 9 listings like 'Star Trek Deep Space Nine Greatest Space Battles SB4 Gum Chase Card', I'm getting 'Your account or listing is in violation of one or more eBay policies...Covid tests are not allowed, even if they are over-the-counter. For more information, refer to our Medical devices policy.'
Huh? These are trading cards, they have nothing to do with COVID tests.
How do I fix this?
Thanks!

Mention of COVID in your item listing, possibly in combination with other keywords, may be triggering that message. Try removing that text.

Makes sense, except that ALL my listings have that line 'Due to COVID, the post office is being slow to deliver', these 9 drafts are the only ones to get flagged. I replaced 'COVID' with 'pandemic', and eBay took the listings.

Who knows what keywords eBay is actually scanning for -- eBay does not reveal that info, likely considering that individuals intent on listing banned items would use that info to hide illicit listings from detection.

There may well be an elaborate ranking of system keywords, and it may change over time. Enough keywords linked to prohibited items in a listing might trigger an error message; eliminating "COVID" from your listing may have been enough to drop your listing below the threshold for detection.
