How did Gobbles prove it was RIAA? (Score 1)

The slightly paranoid side of me says - what if both sides are saying the truth. What if someone posing as an employee of the RIAA contacts Gobbles, gets them to do this and then takes the data for their own nefarious uses. I can think of a number of borderline "legal" groups of people who would be willing to pay someone to produce this type of data for them.

I would love to know from Gobbles how they *know* they were dealing with the RIAA and whether the whole discussion of their deal was done online or not.
