Ask HN: How do stop alerts from Facebook (without deleting yourself from it)

We all know how facebook makes it easy to join in, participate, like, message. But how about removing yourself from groups, pages you liked, etc? I just noticed it takes at least 2 clicks (not counting the load-time between clicks) to leave a group or unlike a page.

It's just unethical that they think you don't need confirmation to join something, but you need confirmation to removed yourself from something.

How do you bulk-remove yourself from (unless) groups and pages in Facebook?
