I think we could kill it by deleting the whole fucking ANN thread, so that the bots could not get a place to lay there eggs. BTW, I have reported the main post.
Usually, if there's enough evidence that they're using a bumping service the thread is removed, and the user might who posted it might even be banned. Although, we have to be careful because if competitors are aware of this they could stage this, and spam to look like bumping services on their competitors, and get their topic removed. It's a slippery slope. Yes, I can understand, there is some misjudgment possible while judging if the poster's are hired by the ANN creator or its just a trap of other competitors to get the thread dumped. But mostly if it is done frequently on a thread with number of newbie bot accounts, I don't think anyone is targeting that thread to be dumped, as this services seems to be paid and no one would be willing to risk it for free IMO.
And ya, you have also made the slippery slope more slopey by mentioning the above idea.
