I was thinking about something during the whole Seigenthaler thing, about the mirrors of wikipedia (I apologise if this has already been discussed, if it has, I haven't seen it). One of his big complaints was that even though wikipedia removed his information instantly it stayed on several of our mirrors such as answers.com and others. Legally speaking, can wikipedia be held accountable for that? My gut feeling is that we can't (mostly because we shouldn't be) because thats the other servers' problem. That is, if they hold old, now nonexisting on wikipedia libellous claims, can we be sued for that? It seems like a case of "Hey, we removed it long ago, if you have a problem with other servers, take it up with them".
Can anyone clarify the legal aspects of this for a poor, legally illitarate wikipedian?
