I'm not making the assumption that it's benign. It's based on my own experience - I've quote stuffed hundreds of times in simulation, and I'm sure it happened in production as well. It's a hard bug to completely avoid. Interesting - the DOS attack is on the exchange rather than other market participants. But could you be more specific on how this helps you make money?

There used to be games where you would attempt to get one order connection on one exchange gateway and then another connection on a different exchange gateway. You'd spam with one connection to slow down all the other participants on that gateway, and use your other connection for your real trades. Other games involved spamming open auctions, settlement trades etc. This gaming was a very brief phenomenon (because it is stupid, doesn't make as much money as traditional trading, and trivial to foil). The exchanges got rid of it almost immediately but it still gets passed around as folklore for one of the "predatory" activities that HFT does.
