I can be emailed at firstname.lastname@example.org. Please do not necessarily expect a response. I get a lot of email and am invested in a lot outside of the internet now.
If you use GPG to encrypt email, you can get my public key here or by running:
curl -L https://michaelvivirito.com/mikegpg.gpg | gpg --import
Do not contact me about selling a product unless you actually understand what my channel is about. Do not contact me with e-celeb drama or other stupid stuff even (especially) if it is about me. Do not contact me if you are a journalist. I permanently insta-block all addresses that do any of this stuff.
If you detect a possible issue with any of my software, it's best to open an issue on either on Github so that you can get feedback from others if I am not available.
