I don't see how anybodys 'Stake' is being diluted? If they post stuff promoting the old peoples home as they have done it's up to members if they wish to support them or not. You did kind of drop yourself in it by saying that you downvoted them because they supported Steemit, that was a silly admission to make in my opinion. You didn't make any mention of them begging for payouts and even if they are I'm not sure that's a reason to attempt to hound them off the platform?

As for "Leeching Accounts" I can give you far bigger examples of individuals who are on Steemit and Hive purely for another revenue stream to complement their incomes from Youtube, Instagram and other Social Media platforms. If you want to downvote something downvote all those "I travel the world" posts whereby the user is clearly comped by the hotels they stay in and the HBD along with their earnings from Youtube, Patreon pays for their lifestyle.
