Why is eBay Port Scanning Me?

Because they can and no one will do anything about it. Also...security.

Recently, I was tipped off about certain sites performing localhost port scans against visitors, presumably as part of a user fingerprinting and tracking or bot detection. This didn't sit well with me, so I went about investigating the practice, and it seems many sites are port scanning visitors for dubious reasons.
