 Re: Is eBay using different methods to link accounts now?
They are likely looking at hundreds of different datasets comparing similar items across a wide array of elements.
It's probably not any one thing alone that is a match that will link you, but the combination of other factors. For example, a matching IP address alone might not link you by itself, but that along with a matching street address or phone# might set up a red flag.
There are less obvious ones, such as photo EXIF data, image characteristics, description details, and possibly shipping/tracking data.
There is no doubt that eBay and PayPal have the ability to use browser canvas fingerprinting. The question should be, do they do anything about it? We all have long known that Amazon does this, only because they actively have linked accounts using it. Amazon's security isn't necessarily better than eBay's, but they enforce their policies differently (and far more strictly) than eBay does.
The best long term security would be implementing a system where their capabilities are not obviously known. For example, they might already know about your 'x' number of stealth account(s). They might not drop the hammer on your right away, though when you make a "misstep". It could be days, week, months, or even years later when you don't know what hit you, or what the actual causes were.
Don't underestimate eBay. They are a Multi Billion$ company with over 15,000 employees and have entire divisions devoted to Trust & Safety and Security. The majority of which is located in a large campus in Utah. They also have access to some of the most sophisticated in-house tools that would rival the US Intelligence community. Don't think for a second they are that stupid.
Do you think they want to kill off stealth completely? Not a chance. They are far more interested in your seller fee money, but so as long as you bring less RISK to them in the way of compliance, or potential legal issues.
