This implies it must be automated not to burden the admins and being automated implies supporting different payments methods and recurring donations platforms... it's a lot of work just to please supporters.
Not to mention it may discriminate people that for whatever reasons can't donate and get what would be a status symbol.
The reasons don't have to be just economic, inducing people to create a trace that leads to their real identity can be risky in many countries.
People should feel welcomed anyway and do not swap safety for a false sense of belonging to a community.
So for me it's 👎🏻
