I think it's not a bad idea to remind people to add a license to their public github projects. It's probably an oversight when they publish code for others to reuse, but don't add a license.

I've had to email people before to ask what the license is.

But what exactly is the point of publishing this bot? Do you want multiple people to start running it? Will the bot create multiple automated issues per repo? That sounds like overkill.

Maybe add a note about that.
