I think they ban by MAC address. I couldn't order a second time after my first SE from my laptop (through a number of different servers), but I tried on my phone and it went through without issue.

My information might not be up to date but for a long time there has been software that can change your mac addresses. However from what I read some time ago, changing a mac address was seen to be pointless as it could not read by the website anyway.
Has this changed in recent years?

Isn't timezone, font size, sytem language and other system info more critical to change these days? See that timezone and computer language system are flags on whoer.net at least.

correct me if I'm wrong, but I think Brave Nightly may be a proper choice to hide fingerprints.
