But buying all the copies is categorically different and I cannot imagine why they would attempt that, except perhaps to prevent their competition from getting a hold of the same text?
Of course they aren’t buying “all copies”, and that wouldn’t even be possible in most cases since such books are usually flea market/attic material and most copies aren’t for sale (or even catalogued) to begin with.
I’d be interested to learn who comes up with such lies though. Is it really just random people venting their frustration, or some kind of organized astroturfing operation?
