I can impersonate another person by creating a fake email address and upload a cohort called “suspicious_terrorists_in_itwiki” which will result in a nicely log entry and story.
For what it's worth, you already can (as in are able to) do this on wiki: just create a subpage of your userpage with a so called "dossier" (it happens now and then). The log would be like one such page of which you can only see the title and not the content.
