WordPress blacklist

Hello, I’m not a wordpress user, but I registered because I need help.
A friend of mine has a blog on wordpress (this one), and mine is in her links.
Today I noticed that the pop-up icon which appears when you put the cursor on the link says that my blog is in the wordpress blacklist (my blog is http://skeight.iobloggo.com). I don’t know why I’m in this list, because I never spammed nor I used my blog to do illegal things on WordPress or other sites on the internet.
I’m not so good in informatical issues, so I wish someone can help me.
Thanks!
