Well, not if you ultimately tie something like WEI to hardware attestation. Then fraudsters would have to buy additional devices, which is not a complete deterrent [1], but would change the economics significantly.

But many here are (in my view rightly) arguing that this would be too high a price to pay for bot/spam protection, since it would almost inevitably cement the browser, OS, and device monoculture even further.

Which a lot of them already do: https://www.youtube.com/watch?v=hsCJU9djdIc

Or just use a botnet to steal use of someone else's hardware, which is also very common for malicious bots.
