Spam On This Blog

For the past two weeks, I've been getting lots of people posting brief comments followed by their website URL. Obviously they are advertising their site. I don't mind helping other bloggers gain traffic to their blog, but now it's starting to become annoying. I've always posted every comment from my readers, good or bad, but now I might have to start screening the comments like so many other bloggers do. I haven't made any changes yet, but if I get one or two more spams, some changes will be made. C'mon guys, lets just talk stocks and try to make some money together.
