The people doing this are those, below average IQ, people who aren't able to fathom how people make money on facebook and twitter. So they come here, hoping that they can make a buck or 300 using steem coins. They are the scammers. Looking for a get rich quick scheme. Instead of spending time building a following, they want instant cash with a single post. And the so called spammers want the same thing. Now theres this silent war between two classes of crooks. The more intelligent spammer and the herd mentality social justice warrior. Both of these will inevitably fail because steem is a scam coin and as soon as ned has cashed out in 13 months, the blockchain will shut down.
