@kravietz verification steps:
1) press windows button + r
2) type "cmd"
3) press enter
4) realise that windows doesnt ship with a whois program and you cant look up the registrars abuse contact
@kravietz also what happens if the user agent is from a browser on a mac? or on a phone or tablet? or on linux?
