Say, for example, like me, you run a directory (like dmoz) with quite a few sites (30,000+). Would you be penalised, if say a site didn't have any link exchange farms on it when the editor reviewed the site - but after a few weeks, that site started participating in these link farms, would I be penalised? As it's damn silly if I was, as I have over 30,000 links (impossible to check), not all are linking back of course.
Any thoughts?
