I don't know if it will stop se spam. It plays a big role in creating se spam so anything it does to curb it will just offset it by the ammount it is responsible for. You have to remember that all types are members here. I have no idea what the ratio of white hat to black hat is but there are a lot of both. If you go to a WebmasterWorld conference you will meet all types. You never know what people are doing. Some of the worst se spam you see might be a highly respected senior member. You may have a beer with an eamil spammer or scraper site maker and never know it.
