The website is pretty & the overdramatic copy is fun, but there's much better fingerprinting demos out there.

The number of data points shown here is low - there's plenty more it could be checking - & a good number of them seem to be wrong (it's only detecting one as explicitly "withheld" but I believe a few of them actually are, leading to garbled output).

Needs some QA.

The overdramatic tone is pretty funny. "You are in [wrong city]. We could send a team on ninjas to kill you right now, but we chose not to. You are welcome."
