Unfortunately it does mean that you guys don't get to see some of the more entertaining comments here on the blog.
Considering I spend a lot of time blogging about infertility and fertility treatments it's not surprising an awful lot of spam postings come from people advertising their fertility clinics in India. Usually it's fairly obvious that the poster hasn't read the post in question (here's a hint, don't begin a comment with 'Congratulations' just because it mentions pregnancy).
Some fall into the word soup category:
I'm not sure what it was about this Frankenstein book review that attracted so many spam posts, but I had dozens of them!
Some of them are rather more concerned about the state of my health, such as this one from another book review post:
You'll notice that one above is also worried about my sex life, but it's okay, because this week's spate of spammers have got that covered too!
Seems like you can get virtual anything these days!
