Un-spamming AW?

Recently I started a blog on WordPress and so reflected it in my signature for AW. To my delight, some AWers clicked to see what I was working on.

Later, when I was looking at my stats, under referrers, there was a tag for AW that said "spam". Wondering what that was all about, I clicked the tag. Sadly, all of the AW referrals are now gone. I'm not positive, but I think I may have unintentionally marked them as spam.

Does anyone know how to undo this? I listed AW as a site that I follow thinking this might help. Still no new views though.

My learning curve is steep on all of this...

Answer found. This seems to be a common problem for inexperienced WordPress users. So if you did the same thing, it cannot be undone after you navigate away from the page. It does not block people from visiting and they will still be counted as views. It only prevents the blocked source from showing up in the referrers list.
