It's crystal clear why they do this. Many companies or persons share their desktops for remote usage. Later they sell this service to eBay users. And they're using it for different fraudulent activities - from making real sales (just for stars) to bidding to own items (for rising price). For years eBay fight this.
I don't understand this could you explain?

He's saying people let others use their eBay accounts through RDC to game the system.
Also it's an auction site. People want to raise the price by bidding on their own items

#23Just wait until the database of ip and open ports is leaked and hackers start exploiting vulnerabilities of softwares listening to these ports to break into random people devices.

In addition, I would expect such a DB to go stale very quickly.

#25I asked this earlier and nobody had a response, so thought I'd ask it again: is there an extension to block this? Edit: @Windows users: pip install pydivert and then try to write a script to block connections from Chrome to non-Chrome processes. you might need GetTcpTable2() or something. (Looking into this now. Check out http://stackoverflow.com/a/25431340 )
As far as I know these port scans are done using WebRTC. Using a browser extension[0] it is easy to deactivate it on the go. Personally, I always have WebRTC disabled by default (as it has several nasty security implications), and only activate it if I explicitly need it for something.

This is a global setting and is applied to all websites. I also wasn't able to test this myself yet. Are there any good extensions for blocking websockets on for specific domains?[0] https://nullsweep.com/why-is-this-website-port-scanning-me/

$websocket
to override this for sites which break use e.g.

#28Has anyone confirmed whether they're still continuing this practice? I'm curious, but at the same time feel highly uncomfortable visiting a website that has no problems exploiting a browser loophole.

It seems like eBay wants it both ways. They want to have a huge user base with low friction to get started, but they also don't want fraudulent players. Instead of doing KYC (know your customer) like many financial services, they're stuck doing dirty tricks like this to try and combat fraud.
