Hi Paula,
Every day this situation changes – as it does every few minutes with the sites constantly rotating. Now I see all the number sites are gone (maybe the dialogue here has pressured him/her to move on) and you’re left with two hnk-art.info sites – and the sites these are bringing up look more and more legitimate every hour.
Our SEO guys stick with their original analysis that the culprit is probably very deep in the trail of links. And, more importantly, that what s/he has done here does not hurt your google search results.
Hopefully, this issue is near closure…
Marcia
