I don't know it for sure, and not sure it can be known other than piecing together circumstantial evidence and watching the price action for a time with suspicion and getting an eerie feeling. You are right though, hard or impossible to determine spoofing from real buying interest.
I don't really know but I suspect because if I was long I'd be worried, and skittish.
