So you're looking to give WowBB a
piece of your mind?

Or are you looking to buy
peace of mind with domain anonymization?

Domain anonymizing is a function of the registrar. LP (actually, Tucows, the real registrar) can handle the .net -- the other two have to be handled by their respective registrars. What happens is that instead of publicly listing you for the contacts, they give a "proxy" contact. If someone contacts through the proxy, they privately pass it on to you, so you can decide whether or not to respond or ignore. Certain legal contact requests (police, regulators, etc.) will still be given your contact information or the information they seek.
I register with RegistrationTek.com -- $15/year including free anonymization.
