You were downvoted by people who were downvoted by a bot themself. This downvote bot pretents to be you for some reason. https://steemit.com/@baissetonfroc
Or does this account actually belong to you? If so, then you actually deserve all the downvotes, you get on this account.

EDIT: Sorry. I just read your post about the impersonation. Looks like you already found out about it.
That really sucks. Sorry pal.
