Thousands of BKs were boosted at the water in York, but who cares? It's a leaderboard, it only means anything if you care about it. It's the same as when you could spar at Sardon's and other places, and when you could PK in houses. Even tower hours are a hugely skewed and ruined statistic (due to the FB merge). I didn't manage to get in on any of that, but why should I care? Just deal with it.
