Today I noticed this Facebook advertisement for legalrayban.jp:

For a change, the landing page today is actually the one indicated. Legalrayban.jp was registered for 1 year on January 20, 2013, by Lin WeiTian. The whois contact information lists a Japanese address and a Chinese phone number.
As with all scam sites, the design is horrible and anyone should be able to see that the site is dubious at best:

The contact information page gives [email protected] as the email address. A quick google search shows that this email is used on numerous other scam websites:

I will report this one to Ray-Ban and see if anything happens.
