The write-up
Inspiration
This project drectly refutes a common misconception that there is nothing anyone can do to combat spam.

Made a PR into the Knots repo
Challenges we ran into
Nothing much
Accomplishments that we're proud of
Making spammers look silly
What we learned
Fighting spam is pretty easy
What's next for garbageman
Making the spoofing configurable
Adding tests and PRing the code upstream
