Referer Spam, AWStats, and Nofollow

Seeing a ton of referer spam lately – which shows how well these “SEO” twits do their jobs, as my logs aren’t public.

Nonetheless, referer logs are a perfect place to add nofollow attributes to outbound links – which would at least reduce the incentive to referer-spam sites.

I use AWStats – there’s already an RFE asking for this feature to be added. I offered a patch to do it – you can grab it here in the meantime. The patch is against v6.3. Basically adds a NoFollowLinks config parameter, defaulting to 1 (on). If it’s on, reported links get a rel="nofollow" attribute.
