If I buy a domain, will people be able to WHOIS me?

[Bret Miyashirp]

Before I can buy my domain, it asks for my name, address, city, postal, email, etc. If I enter false information will people be able to use WHOIS and see the false info, or does it get it through other means? Can they revoke my domain if I enter false information?

I simply can't afford a $10 WHOIS guard, as I'm buying this using ad money from my previous site.
Thanks for the information so far, I don't want to get in trouble with my ISP nor do I want to risk losing my site. I'll just use a subdomain for now, unless I get any more information.
Thanks fruit, have you personally used that site before?
