This blog has recently experienced a massive spam bot attack. It was so serious that the hosting company has to take my site down before I clean up thousands of spam comments from my database.
Well, it is all good now. To prevent this from happening again, I have included some strict spam filtering rules on comment, and also, CAPTCHA plugins. So, you have to do a little math to prove that you are human before submitting comment.
Anyway, in case you were trying to get in touch, but was blocked by the filter or the math is just too difficult for you, please give me a shout in Twitter (@tradergav) . I will get back to you ASAP.
