It’s for donations sent to damus depending on the color of the star, they’re donating a different %
Discussion
Is that donating just through the damus profile or is there another way?
I believe they’re sent to nostr:npub18m76awca3y37hkvuneavuw6pjj4525fw90necxmadrvjg0sdy6qsngq955 when we connect our wallets it’ll ask if you want to donate if any or none at all 
It’s for more than damus. Go to setting to check it out and set up donations of choice.
Snort has it. I’m not on other clients
