Side note on crowdfunding;
Github sponsors is a recent offering from github which is in principle similar to patreon but for open source developers. If you upload the slightly modified frontend to github you can be an open source developer, especially if you actually change anything.
The advantage is that they are matching donations up to $5000 per developer during the first year, the catch is that you can only withdraw money once you have at least $100 previous to matching. So if anons pledged $15/month new admin would get $210 seven months later if they went this route.
Patreon is just a monthly payout but they take a cut rather than doubling your money.
