With its "open graph" system having garnered a fair amount of criticism, particularly because of the fact that it posted the non-Facebook. com activity of the users to their friends' Facebook news feeds, the social network is now coming up with a few developer-level changes, under which apps will be barred from automatically sharing users' activity on the Facebook news feed.

The move implies that there will be a cut back in on the kinds of actions permissible for apps. Towards that end, apps will now have to use authorized actions - such as `Like,' Follow,' `Listen,' `Read,' or `Watch,' - for automatic publishing into the ticker or news feed when they consume content.

Although the new changes that Facebook is bringing on in `unintended sharing' rules will still allow the developers to create custom actions like `run' or `cook', it will be required by the users to click a button if they want the activity to be shared.

With the apps now required to include built-in actions to apprise the users of their activity being shared, a Wednesday blog post by Facebook's Henry Zhang said that, henceforth, there will be a ban on the automatic publishing back of custom actions to Facebook when users consumes content in an app.

Noting that the move is intended at ensuring that the users are aware of the fact that "publishing to Facebook is occurring," Facebook said that, eventually, "the user should not be surprised that Read actions are being published."
