Microsoft said that they've added Vertro Inc. as another defendant involved as an upstream provider of illegitimate click traffic for RedOrbit: "Today, based on our continued investigation in the case, we've sought leave of the court to amend our complaint to add the software and technology company Vertro Inc. as another defendant involved as an upstream provider of illegitimate click traffic for RedOrbit," said Bill Harmon. You can read amended complaint embedded below.
In May this year, Microsoft's Digital Crimes Unit filed a lawsuit in the U.S. District Court for the Western District of Washington naming RedOrbit Inc. and its president, Eric Ralls, in a case in which they defrauded Microsoft's ad platform adCenter through a sophisticated form of pay-per-click ad fraud call "click laundering."
"Microsoft monitors traffic on adCenter closely to prevent advertisers from being charged for non-valid clicks. We're also applying our deep experience in digital crime investigation, legal expertise and understanding of how digital criminals operate to both continue to advance our detection capabilities and take legal action when necessary. With this work, we aim to send a clear message to would-be fraudsters that "Microsoft Advertising is not a smart place to try to commit fraud and that we can and will take action to protect our advertisers," added Bill.
