Thanks Sparkesy43.
Very good and valid question. Something we need to clarify.
It is only for your own posts/comments. Your dustsweeper balance will be used to guarantee that upvotes on your own posts/comments won't turn into dust. Another thing, it doesn't take self-votes into account.
We are planning on releasing an FAQ shortly to cover more practical points like this.
Thanks for the clarity. I'll have to encourage others to get onboard so they can benefit from my votes too. The other question I have, is will members be notified when their balance runs out?
Yes, there will be a notification when your balance is low and when your account balance is so low that your dustsweeper account is disabled.
Excellent. Thanks.
