I just found myself wondering what the hell that little "flag" button is that just appeared up there in the Blogger Toolbar. And, just as I feared, it is a way for blog viewers to voice their concern about the content of a particular blog.
When a person visiting a blog clicks the "Flag?" button in the Blogger Navbar, it means they believe the content of the blog may be potentially offensive or illegal. We track the number of times a blog has been flagged as objectionable and use this information to determine what action is needed. This feature allows the blogging community as a whole to identify content they deem objectionable. Have you read The Wisdom of Crowds? It's sort of like that.
Craigslist has something similar to this to stop spam and the like, or if something is very hateful.
But, censorship is always a touchy issue and usually leads to interesting deabtes. However, I don't want to be told I can't say something sucks, when it does and then be censored.
