not all investors are content creators, nor want to

If investors know that they're not content creators then why they post posts like that?
Its very obvious that that kind of post is not worth that upvotes.
Its greediness IMO.
Many people are abusing the system and Steemit, Inc. just ignore them. If they don't ignore, they are much very slow in dealing with this issues. An upgrade or hardfork is needed on steem blockchain. Maybe they're already planning it or not do anything about it because as we know and see Steemit, Inc. has huge money in there.
