Thanks tim cliff for the post. I did not knwk about spammers in steem. There are people who are posting blogs every 10 mins. I thought they are posting quality posts. But it looks like they are slowing down the system by frequent posts.
I hope delegation of SP macbot and spamminator will reduce the load on blockchain and thereby it will help building am healthy community. It is good the few people are really working hard to get rid of spammers..
