I am also hurt by @clvr on my all comments. If some other bot downvoted our post or comment we can contact them and we can remove from their downvoted list if we don't have any mistake from our side.
But @clvr is a F... downvoted bot written by an Indian. you can see his steemit account here - @cryptolover2017.
Hope you also an indian.Try to contact him and ask him to trow away this bot. A lot of steemian suffered by this bot.
