I know you are only being polite - but they never read ANY of the replies. They do not even visit their own account to see what is posted there (they are supposed to, as they tell you on their site that if you do not want them to post this comment of theirs, just write STOP and they will). Since they never read anything, it does not work. Which is why this is the only account on Steemit that I keep flagging/downvoting whenever they post in my posts.
