And so it seems that Facebook could be proven to be the new groupon.
I would absolutely not be suprised if the hits were FB bots - however I'd expect they wouldn't be that directly stupid so as to have an Ad-bot net in house. Surely this is some service they outsource for plausible deniability.
Something they would have learned from their relationship handing all user data over to the NSA/CIA.
EDIT:
I'd like to make a prediction on how this could potentially play out:
1. FB ignores them. They have nothing to do with this issue and they know the bots are tainting traffic - but they can't/wont do anything about it because it boosts their revenues.
2. FB may or may not be involved in the ad-bots, but, they will drop their $ contingency on ad-rev for the name and payout these guys to shut them up. Their stock was improperly priced and taken a beating. They don't want this coming to light in a large way as it will have a negative affect on the perception of their business model. They hav to be kind of careful of the Barbara Streisand effect here too...
3. Many more people will reveal the same results with empirical testing and it will be revealed that FB earnings are 80% over inflated. Their stock will drop to the predicted real value of <$10... maybe hit that actual projected number of $7.00 - Zynga will BEG FB to purchase them as they are now a penny stock and they can't sustain.
