A federal judge in Atlanta tossed out a bewilderingly complex lawsuit by a group of investors claiming they were the victims of a “diabolical” fraud that netted more than $11 million in a scheme perpetrated by dozens of defendants and a “fictitious” internet communications company.

The claims involve investors in a Georgia-based company, Gotham Media Corp., and a product it developed called VIDGO, described in court filings as “a service that would offer ‘a la carte programming,’ where consumers could create bespoke cable packages, paying only for their desired content.”
