I’m happy when an instance owner just says how much it costs to run a server, how many people actually manage it and how much time they spend to keep it running. I also like it when they just come out and say “we need this much money to keep things running every month, every year, etc”
Then I just donate and there are more a dozen ways people can send and recieve donations.
I don’t mind paying for things and services if the person or people I’m donating to are just honest about what they need and why, especially if it’s a service I use often.
