This is what’s wrong with this whole “value for value” concept, the creators tend to think there is more value in what they say/do, especially if they receive a large donation from someone, then they expect everyone to find the same value.
To use the OP’s example, if I am playing my instrument and someone comes up and drops a $20 in my guitar case, you then start to critique those that donate less because they don’t find the same value.
I said it over a year ago and I’ll say it again, having a per post zap option is moronic and can only lead to dishonesty. The only place your wallet should be accessible is from you’re own profile and only the recipient should see how much was sent and by who.
