As a past owner, the whole "Donation thing" is a bit of a scam to be honest. Now donations do help however you profit 3-5x more than what you need usually per month (Thats what I'm assuming for asylum since they either rent a dedicated box or buy one which can go up to the thousands) When I ran a server on a different platform I got around $1750 in a month. Thats around 20x then what you need, so in a way donations aren't really donations. It's labeled as that, your purchasing virtual items.
