Per meowface's comment, this code is ~4 years old. It's in a much better place now, but there's still a lot of room for improvement.

The vulnerability wasn't in the main application. I'll write more about it on my personal blog in the coming days (http://chrishateswriting.com).

Have you ever thought about re-writing 4chan and making it open source? I think a large portion of the community would be willing to contribute.

IIRC they had open source code called Futabally, but as time went on they closed the sources to protect their interests. Projects like it exist, such as Kusaba X.
