So, shall we remove the admin bit from anyone who admits to knowing how to cause such damage? Or shall we immediately take steps to make it so such damage is impossible?
You're misunderstanding the nature of risk. Our aim is not to remove all risk, that's impossible. Our aim is to reduce risk to the minimum possible while stilling being able to make our encyclopaedia as well as possible. Talking about the level of risk of a certain thing is meaningless, you have to take about the level of risk compared to the gain from it. The gain from 1000 admins is enormous compared to the risk of 1000 admins. The gain from 10000 admins is much small compared to the risk of 10000 admins. In my opinion, and apparently in the majority opinion, that gain is not worth the risk.
