I don't know anything about a blacklist but I can tell you someone made the decision to moderate rewards on the 6 day content and is suggested that your account along with others may have been compromised and now knowingly or not participating in an abusive voting ring consisting of a multitude of others. You may need to change your account keys if I am understanding.

Once that is done, we should have no problems moving forward but I do back the previous call that was made towards suspicious voting trends. Also, I thought the meme would help take the edge off so sorry if you took offense. ✌️
