Really sorry to hear this! Hope you get it fixed, and if there is anything I can do to help, even if it is just brainstorming, feel free to contact me! Something like "United bot-owners agains spam" or something ;-)
Also thanks for sharing this information, I've followed the links you've shared, and found a treasure of information there as well. I'm not against bots (or humans), I'm not pro limiting, I'm for freedom, but when spam and abuse get in the way of freedom of others, it becomes a problem...
