yes, indeed. I was part of a group, an "exclusive" group when I first joined, they rewards they were taking were being used to promote their own posts. the posts they were rewarding were the same post over and over again with very slight changes. They were 2 sentences long and they were taking all the rewards they were getting from everyone and promoting hundreds of those 2 sentence long posts. It was amazing. I am glad I found out and left their app.
