For starters, they have:
- Disabled anonymous editing
- Require identification of editors' real life identity
- Credential verification (e.g. no more Essjays)
But then how can Citizendium prevent the kind of admin abuse currently occurring on Wikipedia? For instance, who get to have admin power, who get to ban users, BLP issues, who gets to decide on content disputes (which are inevitable)?
Just asking questions.
(Also one of the major barriers to Citizendium adoption is that more content is required to attract people - when you Google something nowadays Wikipedia is almost always in the top 10, and Citizendium is nowhere to be seen.)
