I have a policy violation on an item I am selling ( a kitchen sink ) I removed a web address in case that was it and a reference to how much it would cost new was also removed. I cannot for the life of me fathom what the violation could possibly

Perhaps the photo of the box showing the web address

As a general rule you cannot include any links (including non-clickable ones) to a website other than eBay in a listing. I would drop the picture that focuses on the manufacturer/brand's website.
