Assholes who keep spamming the comments in my bloggs

I write thes great bloggs no swearing nd good info and theese guys always put the comments filled with porn site and porn keywords it is not only rude because I have to keep erasing them and they have no relevancy but google and blogger do not let any pr flow from the comments so they are wasting there time. i doubt if people come to my SEO blog to find porn or my art blog stop rapping the blogosphere.

thanks

we know how and where to find porn
give it a rest
this post will get a porn spam i bet ill leave it to show u
