Why do sellers keep jumping on my listings

I am the brand owner, manufacturer, trademark owner, patent owner and sole seller on Amazon.

I keep getting about 8 or 10 sellers, jumping on my listings. They can’t get my product and when I try a test order, it’s always cancelled.

I report them for trademark infringement under project zero / transparency. Then they come crying to me about how I hurt their business and to remove the claim. Which I usually do the 1st time.

My question is why are they doing this? What is the end goal of listing on a product they can’t sell?
