We've all done it: It's only human to Facebook stalk your ex. The relationship might be over, but you still want to know what they're up to, who they're dating now. It's not good for the recovery process, but you just can't help it.

A new program, Ex-blocker, will restrain you when you can't restrain yourself. Just type your ex's name in, and it'll keep you from being able to see your former sweetie's Facebook, Twitter and blog. If you find yourself wondering about multiple exes, don't worry -- Ex-blocker lets you block as many as five exes.

The program launched last week, and already it's shielding almost 2,000 exes from being stalked. Now if only it kept you from drunkenly texting.
