One of the (many) problems of anti-social behaviour is the amount of curators' time it takes up - the opportunity cost is huge. What I'd like to see is a policy where poor actors are dealt with as "business as normal" - quickly, quietly and without drama: the average poster wouldn't be aware of it. This is housekeeping, the same as we'd keep the beach clean, the bar stocked and gaffer tape in the tool pan, so reggaesteem is a nice place for people to be.
