@Len - Yep. I've seen some large well known sites with comments just like the ones in Viktoria's post. I guess no one is paying attention or is too busy to delete them.

@Viktoria Michaelis - I've received comments that are spot on in terms of being relevant to the article they are responding two but I've had to delete their link because it's to some spam site or marketing space. So I end up leaving the comment text but deleting the URL so I get the last laugh.

@Grumpy - What's that like? To silence entire countries?
