1) The social auth tool we're using only allows you to have one set of permissions, so we're using the default set for our overall application. If you see my earlier comment I did update it to be a little less ambitious on the permissions.

2) The list of likes comes directly from FB

3) There is an endpoint provided by the Facebook Open Graph to delete a like. However, you have to be whitelisted by FB in order to call that endpoint.

4) Yeah, the thought was that you'd come here to unlike pages. If you made a mistake in unliking a page that you want to continue supporting you can go back there on FB and re-like it. The reason we removed the button after the action is that it's crazy confusing to explain to someone how to unlike a page using the default FB like implementation (the only implementation) and I'm sure that's by design. If the button stuck around after the action, I'm sure that there would be a lot of unintended re-likes.

Thanks, we're trying! Our goal is to help consumers voice their complaints to large companies (that aren't always listening too well). Please give us more feedback!

Thanks!
