So I didn't explain it well. It is expected to be working in a way that you receive more than what you send.
But more importantly, it takes care of the dust others create on the comments of the subscriber. When they are almost 7 days old. It is not about your dust votes, it is about the dust votes others give you. So the receiver of the dust vote should have the subscription.., Well, maybe I am not the one to explain it. Since I am no specialist. But there's the name of the account I gave you. And the blog and the associated names of people working on it, also their Discord can be found, etc.
Oh yeah thanks for the explanation I was just googling about it. Yepp it seems it takes care of the dust I would get. I'm not really that concerned about it. My main encounter with dust is here under my posts where I used to upvote everything with 1 cent which doesn't make any sense actually :D But thanks a lot for help! :)
