First of all I would like to suggest to @ernest to take a day or two break from working on kbin and in general to not overwork himself.
Secondly, some sort of Patreon should be setup to streamline the donation process. I, probably like many others would like to just set up a recurring donation and forget about it.
Thirdly, I think it would be great we also have something like https://beehaw.org/post/428209 to keep this as transparent as possible.
Since kbin.social is exploding these days, perhaps what is most urgent is lump sum funding at buymeacoffee to cover any necessary hardware upgrades.
Down the road, some sustained funding will probably be necessary, but hopefully many other instances will be created so the load can be spread among many servers/devs.
