You seem to be assuming that my comment was the result of some failed campaign. It wasn't.
Surely you would concede that your $3M campaign was a rarity and could not be duplicated in the case of most advertisers. About 30℅ of casino players walk out winners on any given day too - it doesn't mean they are going to beat the house long term. If you are advertising on a medium where useless metrics are the desired goal of your competitors (likes and shares in the case if Facebook), you cannot beat those people if you need a cash ROI and they don't. There are always going to be exceptions to the rule, and I'm glad you found one, but that doesn't invalidate anything I've said.
