Exactly the problem. There are many 'communities' where people simply input each other into their bot-voting system, and don't bother to read each others' posts. A worthless community that causes problems for others because they put worthless posts at the top of 'trending'. There are a few things like 'curie' , 'whalepower ' , 'history-trail', and 'minnowresteemer' where someone actually reads the posts, and then votes them, or shares them if they are any good. I am actually going to go back to using wordpress for more serious things, even though I don't earn anything there, because it isn't about posting junk over there.
