I was thinking along those same lines earlier today when reading a post. The scammers will detract from the site and as a member, I know they distract from my enjoyment when I am scrolling through new posts to find some content worth reading. I want to see the site prosper just as much as anyone, so I spend time and effort to post decent content and comment on posts that are worthwhile. I upvote every time I can if the content is valuable to me and I honestly gained something from reading. I think if we take the time to reply back to those who took the time to read our content and actually engage in interaction then things would pick up. I do what I can even as a newbie.
