This was too obvious, with your comment right next to an identical one.
Tell you what: search out "how to interact positively on Steemit" and variations, explain to me in a comment why spam comments like yours and @sojib24's are not welcome, and that you won't be doing it again -- which anybody can verify, Steemit is an open platform: https://steemit.com/@muhammadkamal/comments -- and I'll remove my downvote.
It seems almost every single one of your comments is copy/pasted, matching the above. Please stop, your reputation is at stake.
Is there some bot for sale that does this for new accounts? If so, your money's being wasted. If not, we know two accounts share an owner, or at least, "learned" from the same process.
