Scam attempts are becoming more and more frequent. There is a user in the steemit.chat "mottler" that try to confuse people with the real steemit user "mottler" that his 100% upvote worths around $300 usd.
He asks a transfer of 10 Steem to his bittrex account for upvoting 100% two posts. Be aware of this user and if somebody administer the steemit.chat must ban this user.
Thanks for bringing this up.
