MSNBC Peddling Porn on Blogs Using BlogAds?

I was surprised (not in a pleasant way) to find MSNBC, which has rented space on my blog through BlogAds is apparently peddling porn on that space.

Their ad reads “Welcome to Porn Valley” followed by “MSNBC 12.14.2005″ (look on your right). The reality is that they are peddling their online magazine which apparently no one reads (I know I don’t). It still makes me angry.

I am angry because when I initially accepted their Ad they were somewhat off-color but still acceptable. Now after accepting their ad they decide to switch it. That wasn’t what I bargained for. The only thing going in their favor is they are not peddling porn but their magazine, which apparently in their infinite intelligence is on the same category as porn.

My question to you as a reader of this blog is:
Do you think I should continue to display this ad?

Update: MSNBC reverted back to their original ad without the big “Porn” word. Their effort got mentioned in New York Times, which also mentioned some of the participating blogs like Gothamist, Adrants, Althouse etc. Neither this blog nor BlogAds (who organized all this) was mentioned. Bad NYT, very bad!
