I don’t do this kind of thing lightly, but it might be a good idea to post this on your wall:
- Facebook found a problem in the way that it was authenticating applications.
- Any time you used an application a token was created that would allow the application to do it’s thing — including posting on your wall, accessing photos or whatever other permissions it requested.
- The tokens did not expire and were being “leaked” through normal operation on Facebook.
- Anyone who found a token would be able to use it to do the same things that you allowed the application to do — including posting on your wall, accessing photos or whatever other permissions it requested.
It is important to note that Facebook has said there is no evidence that this has been exploited — yet.
The problem has now been fixed, but all the old tokens could still be usable until September 2011. You can re-secure your account by simply changing your Facebook password. This will invalidate any of the existing tokens.

I’m a huge fan of bloggers (and podcasters and well… everyone else for that matter) using full feeds for subscribers to their sites. I’ve got no time for people who demand that I hit their website to be able to read the content. If you want to monetize the feed that’s fine, but let me read it where I want.
