I was assuming that there was an additional data source, such as aerial photos and/or GPS traces, which could be used to judge the accuracy of the tainted node. As I understand the way the bot judges taintedness, if you delete a tainted node, then insert a replacement node in the same location, the new node is also considered tainted even though it was added by someone who agreed to the new license terms, and even though that might be the correct location to mark the corner of a polygon. -- John F.
