An interesting thread has been started on the SEW Forums regarding a paragraph in the Wikipedia External Linking Guide. It discusses the possibility of sharing link spam data with Google (and presumably other interested parties) in order to monitor and potentially penalise spammers.
The idea is still more of a suggestion then an official statement of intent from Wikipedia, although it would be interesting to see whether existing records of past link spamming would also be shared (opening up a can of worms for SEOs who use such tactics).
Is this just an off the cuff remark by a rogue editor? A warning shot across the bows from a tired Wikipedia? Or some other idiom which I've yet to think of?
