No. I've been considering whether to open source it, and there are two issues:
- Due to the current lower prices, I haven't nearly covered my learning/development time yet from the community rewards, significant though they have been.
- If this code was made public it would allow organised spammers to much more easily circumvent adverse classification, and undermine the effort.
I think this issue is similar to some we've discussed in the past, with no obvious perfect solutions.
