I was notified about this guy and he was added to the blacklist.

No need to be upset. This type of issue only takes time to rectify. I am actively pursuing ways to help it. In fact as of yesterday I am now also working with steemcleaners for just this reason.

As this post states, if you see people gaining votes that are scammers just let me know and I will blacklist those accounts. :)

Ps. I also removed my vote from his post :)
