109.69.108.176 attack
tried to spam in our blog comments: I'm amazed, I must say. Rarely do I encounter a blog that's both 
equally educative and engaging, and let me tell you, you have hit the nail

I am very happy I stumbled across this during my hunt 
for something relating to this. url_detected:www dot ergoplus dot it/?option=com_k2&view=itemlist&task=user&id=2671553
