I didn’t know this before, and it could conceivably help if you happen to be trying to track down a troller by incoming domain name or e-mail address and you find inaccurate WHOIS information.
There is a way of dealing with false WHOIS information. You can report it to the InterNIC and they will process it and try to rectify it.
You start with this form (the Whois Data Problem Report) and follow the directions there.
The form does require your real name and a functioning e-mail address, so it will leave a paper trail that could conceivably implicate you should someone track it back, but it’s a good tool to know about.
