+1. Add new flag $Spot::no_node_in_dupe (default: 1) which disables including
+ the origin node for spot dupes. This should stop people posting the same
+ spot simultaniously on several nodes at once. Or at least just ignore all
+ the "duplicates".

+ done originally and there was some reason to include the origin node.
