This is remarkable. Concert tickets are also being bought this way by bots for scalpers. Ebay sniper bots are commonly used. High Frequency trading is the high end this. Perhaps it is unavoidable, perhaps other means for selling things online should be sought out, text messages with semantic replies required or something?
We're in a capitalist system, the price you pay the scalpers is the "real" price of the concert: it's the law of supply-and-demand.
Now, if scalpers win every time, this is an issue with the original ticket sellers, not the scalpers!
If Shell started selling petrol at half standard price and some guy comes round to fill up a tank and then sell it to people at 95% standard price, that's Shell's mistake, not evil behaviour on his part.
