The patrons are really the biggest mystery in the gnome-o-verse. He has 93 of them, but by comparison only 86 people have replied to him on Twitter 10 times or more and at least once this year. And of course his "real friends" on Twitter surely number less than 20. Whoever's donating to Jake, a lot of them apparently don't interact with him at all, or barely.
I'm sure there's at least one family member on there, and maybe a Talking-Time weirdo or two, but Jake pretty much doesn't exist anywhere in the world, online or offline, except Twitter. He's necessarily being funded by people who don't want anything to do with him.
I don't think "abandoned Patreon accounts" is the answer either, because this has been going on for years and we don't see a steady dropoff as credit cards expire. I wonder if there's some subculture of people who have so many $1 subscriptions that they just don't even remember how many or to who.
Also, he had just about no patrons at the time of the October 2015 Patreon leaks, which wasn't long before his excommunication from CON. So I doubt this is all Gamergate leftovers.
