There's a steemit.chat message spammer pretending to be you and begging for SBD. Even sends a link to your account. I doubted it was really you due to the poor grasp of English he/she/it displays, and the request for money was the last evidence I needed that it probably was a scammer.

EDIT
I wrote a brief post and used screenshots of the chat. I hope I made it absolutely clear that no one should think this is actually you on chat. This kind of scam is cancer to the community.
