It's not about the numbers. It's about people. Right now not a single individual can be trusted not to misuse somebody's personal details, through malice or negligence, and not create a severe risk for the owner. Being one in a narrow selection of computer professionals doesn't help much. One can be a genius and a person of low ethical standards at the same time. No solution until the civilization progresses much further than what we have now. Until then, lock down the Whois database. Even better, discontinue it altogether. Let individual registrars hold the personal details of their customers. At least it will remove the risk of compromising everyone's privacy with one action by not putting all eggs in one basket.
