Yes, and I know it's counter to the core motivations of this movement, but probably need a centralized repository for donation that can be a universal door for funds that can then be distributed to vulnerable, but active, instances. Needs to be run by a collective of reps from instances meeting a minimum threshold of support for the community. Also needs to be nimble enough to revoke funding is an instance takes a hard evil turn.

Or maybe just an app/site that recommends a distribution of a set monthly amount (e.g. 30 bucks) to the instances you use the most as a user?
