This week, Microsoft filed four new lawsuits against alleged spammers, brining their total anti spam suits to 101.

A suit against OPTIN GLOBAL, alleging state and federal violations, follows on the heels of last week's action filed by the FTC and California Attorney General in San Francisco. Other suits against "didyouknowclub.info" and "hoolamaco.biz" were brought exclusively under the "sexually oriented" provision of the CAN SPAM Act of 2003. All four Microsoft suits were filed in the Superior Court of King County, Washington by Preston Gates & Ellis LLP.
