Hey Mark, I noticed you put @justyy in a blacklist and down voted a good post of @ericet
https://steemit.com/hive-180932/@ericet/voice
I want to know why did you do these?
@justyy is not a top witness, but he developed many applications for Steem. Are you aware of that?
As a top witness, what's your contribution to Steem? Have you done more than @justyy? Please educate me. Thanks
