Does it or does it not open unsolicited issues on GitHub repositories automatically?
Seems to me like that's exactly what it does. If it does, this is the epitome of spam despite your claim otherwise. Your attitude and apparent disbelief that this would be unwanted and disliked by people is baffling to me. Just look at most comments so far that have felt the same way.
Going back to other comments, many people store dotfiles on GitHub which aren't likely to have many stars and which would be entirely reasonable to not have a license for.
Moreover, if this bot ever opened an issue on one of my repos for this, I'd flat-out report you to GitHub for harassment if they didn't already beat me to it.
If you want to create a website calling for people to add licenses to their projects and start a movement that way, great. Just tell me where to sign up for the cause. But this is just plain wrong.
