Re: Managing Public Comments
There's a "webmaster report" option that puts a link in the page footer, to report inappropriate content. This appears on every page. That is it's function, but I'm not sure how conspicuous it is, although it could be made more obvious with CSS and/or a text description, etc. elsewhere in the pages, if necessary.
There's no automatic way for something to be deleted if it gets multiple reports. I'm not sure if this would be a good idea. Someone with an agenda could delete things just by registering at the site under three names, for example. Maybe a system could be created for this, with just trusted users being able to report objects, but there's no mechanism for it yet, as far as I know.
