Nobody will take your call the second you step inside a jail. Best man at your wedding? He's not picking up, I promise you. Literally nobody will call you or write to you. You will get nothing except maybe from your mother. If you are married, forget it.
Humans only like to associate with success. Once you seem to be failing literally nobody will want to even speak to you.
I wanted to contact him to tell him that he was wrong (he got to the front page without using any of his proposed techniques [1]) but I couldn’t find the e-mail. I have no LinkedIn either; right now I almost feel like submitting an issue to one of his github repos just to get his attention. Can you point me to his e-mail address?
Even if someone doesn't have a public email address on their GitHub profile, you can generally find a routable one in their commit messages. A corollary is you shouldn't use a non-public email address in your commit messages.
If you're lucky, you've got a wife or parents that'll write to you or take your calls.
