Some moron thought that it would be 'funny' to link a really revolting pornographic photograph into a random article, and unfortunately before I could remove it I had to LOOK at it.
Anyway, if the image had had to be uploaded it would have been caught in the net, but the jerkwad could just put http://etc and the picture showed up on the page all by itself.
I know that 24.70.159.4 is probably a random passerby with a perverted sense of humour, but it was gross and disgusting and made me physically ill. Oh... looking at recent changes the same person has been hitting a myriad of articles in the last fifteen minutes. I just blocked him, and I see I was the third person to do it.
