Spam, Spam, Spam, Spam, Spam

So I want to talk about Spam, not the tinned variety that I have nightmares about - spam and tomato sauce sandwiches which made me retch -yes really - I swear I will never put my kids through anything so hideous!) remember, but the electronic type of Spam

I am taking part in the A to Z Blogging Challenge and one of the criteria is to turn word verification off from your comments so it is easier for visitors to pop by.

Having duly done this though I am being spammed, the latest about genital products, yesterday I could enhance my manhood - bit difficult seeing as though I was a female last time I looked and loads with links in which quite frankly I would only click if I were VERY stupid but we are only 4 days into this challenge and the Spam is really doing the old noggin in already

I am going to take to the great oracle twitter and ask for advice but has anyone got any advice on how to Banish the Spam? (other than turn word verification back on)
