I have been using SP and it is a great resource for me in my SEO. But now a days i feel there are newbies who have just 5 posts and ask a question and give a link in the question (eg Why my PR went down and giving some sitename). We people never doubt as if he is a spammer but we suggest him different answers. But what i feel is he doesn't need our answers perhaps he needs to get a "Do follow" link. Why SP is not strict as before.
