@conradt remember my saying I was 'nutty'? If I get a reply to a blog post, which has an advertisement for someone's 'cause', I consider it an unwanted advertisement (spam). Like if I placed a link to my training group in here.
I love the idea of SBI, and would really like to see it take off. (if it takes off as I dream it could, it would displace governments :) ) What I wouldn't like is to have a link to it placed in a reply to my blog post.
That and free money from a bot-upvote seems to be counter to my idea of quality content (though I do understand they are separate issues)
Thanks for taking the time to ask.
