You ban only dMania and no meme authors on Steemit or decentmemes.
Did you even check anything before submitting that statement? His post before this one literally bans some users from using the buying of votes and @themarkymark has done a lot in the past to prevent abuse of it with manual curation which I wish others running vote selling services would do as well.
I voted this post up cause I believe it's a right direction in preventing people from buying votes for low effort copy-pasted "memes" which you yourself are encouraging due to the way your random voting bot curates.
I don't have anything against him banning users who use voting bots for the decentmemes tag either, there just isn't any incentive for them to use voting bots on those posts because there isn't a bot waiting to vote them up with delegation if they are on trending/hot list.
