True enough the dollars to reward might be low, but we really don't know what the final results of the program were. I can only assume that data vetting was part of the planned operation, but the army has surprised me before. Even with limited success this may have been deemed worth it since it only constituted .5% of the pentagon's funding.
Also you are correct I should have specified that this was a black psyop instead of just black op. The difference didn't seem that important, but I guess it's the same to you as someone calling a bradly a tank is to me.
On on a side note psy op or truth, I don't think Russia could make the upcoming election worse than it already is. No real fear has come of that one because we have bad and bad as our choice this year.
