I agree. I think all posts should bring some value. I think that it is up to us as voters to only vote on good posts whether they are promoted or not. If it isn't profitable to post crap posts, they will stop being posted. I think it's mostly unrelated to whether it's promoted or not. Thanks for reading and the great comment. I'll be sure to most about the accumulating probability algorithm in the future. It's simple but it works for what I need it for.
