We have the mechanisms in place, but it appears we need to attract more knowledgeable people. It's the ignorant ones and the vandals who cause the problem.
We can either keep our eyes open and handle problems as they arise and improve the technical means we have available to deal with issues or get rid of the people causing the problem, but it's already clear that removing editing priviliges of anons or severly restricting them on any editor is not going to get community approval.
