@thibaultmol @alan @mihamarkic @djh I was thinking that this time the vandalism was quite big. If, and that's a big if, we assume mappers are human, why not try to impose a human paced editions? iD already tries to keep changesets small and how many changes a human can make per hour?
hmm....
but then it's just a matter of creating new user to circumvent it. :(
