Pyramid schemes built upon forks of the Bitcoin software ultimately discredit and harm Bitcoin's reputation.
Attacking and killing them serves to provide ultimately more discredit to the entire project than just letting them slide into oblivion. What you have achieved here is simply wasting your time to no productive end.
I partially admire Luke for at least having the courage to push those pump&dump forks right where they belong.
What I don't appreciate is the execution, how many people mining on Eligius would consent to this?
(If I got paid regardless, I probably wouldn't care though)
