• Scam

Evidence:
https://steemit.com/upvote/@sweeper/free-steem-dollars-giveaway-18-december-steem-return-on-investment
He sent only 0.048 SBD to mckenzie259.
Yet, @hr1, @tecav, @rxhectordali. soh, @pompe72 @taspingo and many others voted.
Plus, his post is worth $0.69 on steemit. It is not possible that he won 0.048 SBD with it.

Conclusion:
He scams the users, rewarding only one voter not proportionally, to believe that he does it randomly.
