Well I think there is a difference... On one hand you got the comments, just begging for followers with no addition to the discussion/question/whateveritis... But if you first write something, putting some of your time in it, I don't think it is wrong ending the post with a polite question to upvote or follow...
But that is my 2 cents
Simply writing follow is still ok.
Follow, upvote and resteem is royal begging.
Money makes people do weird things.
