Be careful of scammer

Hello everyone. Almost one hour ago an user ping me privately in steemit chat and ask me only 10 sbd to about my 5 posts and every post will earn 15 sbd. His chat ID is : https://steemit.chat/direct/booster. In this ID I found a dot at the end of the ID which looked unusual to me. Then I searched and found the real steemit chat ID of @booster: https://steemit.chat/direct/booster which is read only mode. I took snapshot of our chat which I am going to publish on my post. I'm not sure but I think he is a scammer. I would like to convey this message to every steemian so that they could become watchful these types of users who might ping them too and ask for sbd in exchange of their upvotes. I think he is fake.

I also searched his steemit account but I did not get the same user id on steemit. I told him that I will send my SBD in your steemit account, but he wants the amount in his bittrex account as he wants to save it separately. All these things indicate that he is a scammer. So be careful.
