If the amount of the websites which is annoying and not trustworthy is bigger than the amount of the site which are trustworthy, than we may have a problem. The con artist of this world who had specialised of the Internet are doing well, that is for sure and no one can stop them. Everything you can do in $, you can do in BTC now and even easier and faster with an anonymous payment.
in the 1990's many people were afraid to use their credit cards on websites due to scam sites. financial regulation did not solve this problem. consumer protection did. EG businesses had to register with their state and search engines monitored phishing sites.
bitcoin sites will do the same, if th site does not look legit and does not have legit 'whois data' dont use it. report it!
any legit business, no matter what currency it uses, should not have who-is guards. leave who-is guards for the shady illegal businesses and accept the risks that if your dealing with shady criminals, expect to get extorted.
