I Lost my 28 reputation when a whale hit me without any reason.

Hello steemit a whate @adm just hit me and i lost my 28 reputation. But he did not mention the reason of downvoting my post.

i just want to say at least tell me the reason of downvoting my post because i am not a professional writer or blogger maybe i did something wrong but my concern is if are are downvoting someone post atleast give a reason.
