I sell (or used to) tins of wax specifically created to protect Bushcraft knife blades. its called Outdoorsman Leather and Knife Wax Balm - that's the product.  Every month since March eBay's AI system has been removing the listing, and every month I've spent hours getting it relisted.  It's a tin of wax!  
This month I've had to spend the time twice, both times with escalations to get the ban lifted.  They haven't got back to me - fist time over two weeks, now currently a week and waiting.   
I could change the listing title, but then people who need the product wouldn't be able to find it.  
System sucks since AI arrived on scene.
