What makes the Kitchen's spam target YAF? I see it on this board and on mine I am deleting accounts/posts every day. What is about YAF that's attracting this? I'm sure they do it to other boards too, but in all of them that I've checked, I don't see it. I'm not picking on YAF, I love it.

Edit, searched for kitchen spam and one of the first links ... there are a few more YAF boards and then going from link to link, some phpBB boards. So, this isn't a YAF only thing as perhaps it could be percieved I was implying. I'm just trying to figure out how to stop it.
