WMT are very fast to add new links but very slow to remove old
I blocked 2,300+ links from a suspect site - looks like negative SEO that has paid off, as previously posted - on 8 May. Blocking took immediate effect on the backlinks, but they have only been disappearing in dribs and drabs in WMT (1,373 still showing this morning).
By the time they have all gone AND Penguin has run again my site will have been out of the picture for the main two-word money term for a couple of months at peak enquiry time.
