I think the missing aspect is that the platforms put this stuff in front of your face and human curiosity will have your attention directed at it anyway. You will actively be thinking about that troll who opened up an issue or someone in your Twitter DMs asking for help.

Although I respect the author's boundaries, that is sadly just part of the job of putting your work on the internet. This does not just stop at open source, if you put anything out for the world to consume, do know that this is what you're signing up for whether you like it or not. People will "find a way" to contact you and won't read your boundaries or even know about them before they do.

I keep an autoresponder in a notes file that I copy and paste regularly as it's a full time job to keep up with the requests.
