People, just because a domain can have whois guard means you're protected.
If you want to make sure they can't get to you personally, buy domains with a pre-purchased, disposable credit card, and do it from an internet cafe.
Any of the domains I want to use for dodgy crap, I do that with.
No link back to me, unless they're investigations department is so good that they track the time in which the credit card itself was purchased, and where from, and then go get the security footage from that 7-11.
