In my experience this is not new either; it just seems to be getting more attention lately - perhaps because Google are notifying some people.
I cannot fathom their behaviour:
1) Allow malicious SEO to work... duh.
2) Then actually tell people that it works... double duh.
3) Then confirm exactly the type of links you need to harm a site's ranking... triple duh.
