Exactly I’ve been walking with Steemit learnt that Wrong Comments may get Flag and finally drops Reputation. So we can save our reputation from Flags by avoiding Wrong Comments.
We Can Follow Just These Simple Rules
I have learned about to do not put a comment as generic like as "Thank You", "Great Post", or "Thanks for the info,". In Steemit community that’s one kind of Spam. Adding some post related word with this generic comments.
Avoid commenting that clearly intended to promote own post that is not related to author’s post. Maybe your intended post is quality full with other topics but all readers might be not interested in that topics.
Do not make negative comments about author’s post or comments. The author might be affronted by your comment and you might be flagged by an author.
Avoid change meaning of your comment that very surprising after up-voted it. Like as from “I Love Steemit” to “I Hate Steemit”.
Do not make the same comment over and again under same content. A reader may mix up you for a bot through your comments history.
Never ask for Voting, Following and for SBD directly.
