Cyber Monday was a bad day for buying knockoffs

The federal government zeroed in on websites selling counterfeit goods and copyrighted materials.

Authorities have seized 82 domain names of commercial websites, stopping the sale of thousands of counterfeit items like fake Rolexes and designer purses.

Also targeted are illegal copies of music and software.

Billions of dollars are lost every year when consumers, sometimes knowingly, but often not are sold fakes.
