Instead of getting upset at all the spammers posting junk in your blog, I suggest you have a laugh at it. Read through the content before hitting the delete button. It is amazing how terrible the posts are in terms of content and grammar. Not only does it not make sense, it makes you wonder if a human could be this bad at english.

Read the following paragraph for example:

They say that the number of spam in your blog is a good measure of how visible your website is on the Internet.  I’m not really one to believe that but if you think about it again, there seems to be some truth behind it.

At one point in your blog’s life it was still new, you just posted your first blog and the whole website was not yet properly optimized for the search engines.  Time goes by and you are able to build backlinks for your blog, participate in forum discussions, submitted your ideas to article directories, spread the word via Twitter, and made a fan page on Facebook.
