Hi, sorry but this is simply not something I'm interested in implementing.

Further, please remember that GitHub maintainers do this for free, on their own time.

Thanks!

Anything more than that, block and move on. I've been on GH for 10 years or so and it's gotten really bad in the last few regarding pushy dickheads like this.

You owe nothing to them, and if they can't behave within the OSS ecosystem then they're going to get blocked. Plain and simple.

In the past, I've simply responded to drive-by PRs with "No thank you :)" and closed them. Not common but sometimes people do stuff that makes no sense and you just can't really say anything other than that.
