Ebay scammer alert (story in post)

Sorry if not allowed but I want to warn people, I had listed a lot of 74 cards for sale from 1993 Marvel Universe. Had a listing with 2 pictures, one being stack of cards and the rest being the cards laid out. Im used to people asking questions about these kinds of lots and happily answer all questions and send more photos and have sold many over the years with no issues.

However, I got this message earlier, and they proceeded to follow it up with my first ever negative feedback in 12 years of selling. Can I do anything to get the negative feedback removed? Also sellers beware!
