While it's true that your #dustsweeper balance would get quickly depleted if you have many comments that needed dust-sweeping, you get the equivalent Hive Power for that, which is practically just like indirectly Powering Up your HIVE tokens !INDEED. 🤔🤓 There's also the dustsweeper guarantee that just in case they tried to sweep one of your (incoming or outgoing) dust votes and the vote(s) still turned to dust, then your balance won't get deducted for that vote. 🤓😏
