> honourable deed of selflessly improving open source science and maths projects

And yet it's doing trivial things nobody asked for and thus creating a load on the already overloaded system of maintainers. So it achieved the opposite, and made it worse by "blogging".

This is what I think was the big mistake by this bot. It took a problem which was too easy. If it actually solved something for the project I think the conversation would have gone differently. Just out of curiosity some maintainer would have at least evaluated the solution at high level. That would have been progress.
