How do you determine what is overvalued content?
You upvoted your own comment (something I don't have a problem with) instead of finding a quality post to upvote. In many people's minds, this makes it overvalued...
I don't like flagging on the site at all, but that is just my preference...
Self upvote of comment is to attract attention and jump over all the thanks posts.
There is definitely a gray area of what is overvalued. A model could be developed comparing Steemit Article Quality verse Freelance Writers. I do not even know what freelance earns per article but I am sure someone knows the answer.
There are definitely some black and white cases. The other day I saw a post commenting on one individual with $28 comment self upvotes which were all just thanks or other spam.
