(CBS/AP) NASHVILLE, Tenn. - The 21-year-old who bragged online about hacking Miley Cyrus' email and distributing revealing pictures of the then 15-year-old singer, has pleaded guilty in a Nashville federal court to separate charges.

Josh Holly admitted Monday to having about 200 credit card numbers that didn't belong to him, and to commercial electronic mail message fraud, in a scheme to spam visitors to celebrities' MySpace pages.

FBI agents raided Holly's home and seized his computer in 2008 after he bragged extensively online about hacking Miley Cyrus' account, and found evidence of his other crimes.

On Monday the 21-year-old Holly also answered for violating a condition that he stay away from the Internet while federal charges were pending, reports the Tennessean. According to the Tennessean, Holly said he believes he has an internet addiction.

Holly faces a maximum of 13 years in prison and a $500,000 fine. Sentencing is set for Oct. 31.

He has not yet been charged in connection to the leaked pictures of Cyrus.
