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.
