OTRS means we re dealing with those cases where the person is aware and kicking up a stink we need to take action everywhere but especially where attention isn t already being called to it those complaining to OTRS are already better off than those not doing so The metric of multiple vandalism is very sensible it is a measure of where someone has enough badwill in the world at large to attract problematic edits in the first place Your metric of vandalism not reverted in X seconds is also sensible since it shows where problematic edits are likely to persist Both where likely to be created and where likely to persist are sensible points to focus on I m not sure how you can argue otherwise D
