I thought so too, but the occasional restriction (e.g. Namecheap prevent using WhoisGuard on .ca&#x2F;.uk domains) makes it seem like the technique isn&#x27;t generally applicable.<p>On second glance the submitted article doesn&#x27;t specifically mention WHOIS - perhaps i just read too far into it and it&#x27;s only intended to stop junk data, which is a lot more defensible.
