Have you been following this story? Roca Labs sells "neutraceuticals" that it claims on its website create the same effect as a gastric bypass without surgery. Many unsatisfied customers who bought Roca Labs' products vented on a website called Pissed Consumer.
Roca Labs, pursuant to a clause in its contract with customers, turned around and tried to sue Pissed Consumer for interfering with Roca's contractual relations with its customers. Pretty prosaic stuff, right? That's just the tip of the iceberg.
