The alternative is to establish good dialogue with the communities you are monitoring (the US on this case), and make sure there is awareness and buy in to your proposed action. I don't think that would be difficult or time consuming but does take consideration of other mappers in OSM who you don't regularly communicate with.

> There is no such thing that gives anyone the right for large scale vigilante actions. There is enough justification to potentially take action (after discussion and with proper communication) -- sock puppets for one -- that you don't need to invoke organized editing.   If and when we do have a policy, we in the osmf will also need to develop clear guidance on how it is communicated and implemented.
