WASHINGTON (Reuters) – U.S. investigators said on Wednesday they had arrested an America Online employee and a Las Vegas marketer for stealing the Internet provider’s customer list and selling it to a purveyor of “spam” e-mail.
AOL members were flooded with millions of unwanted messages because of the scheme, according to a criminal complaint filed in U.S. district court in New York.
Jason Smathers of Harpers Ferry, West Virginia, was charged with stealing a list of 92 million AOL customer screen names and selling them to Internet marketer Sean Dunaway of Las Vegas.
