OMG I Got SPAM

So after I get home today, the first thing I do is to check the comments, and I find about 15 SPAM!!! They are deleted immediately. I feel panic, but at the same time, I'm happy that someone wants to spam on my blog, which means my blog is getting the attention. It also makes me excite on how to counter the spam; therefore, I change the CAPTCHA image in hope it can prevent some spam. I hope this post won't provoke more spam ^^;
