The solutions: #Disallow living bios altogether - far too drastic #Drastically raise the notability thresholds on bios - possible #Restrict anon editing etc in Wikipedia, or require some scrutiny of editors - possible, but the whole project will suffer #Fork off all living bios to a separate wikimedia project with specialized rules/community etc (a 'wikipeople' or 'wikiwho') - should be considered as it would allow tough rules here - whilst retaining eventualism on the rest.
#Use stable versions in some way - I think this is our best option. Once the stable versions software is finished we should be able to use it to make fact checking more feasible.
