Apparently it does make it enforceable as they removed his page. Unfortunately when you're on someones platform you're at their mercy, they can delete your page for some minor infraction and you've got very little recourse.

I suspect they removed his page because they can't take action directly against him.

How would it be illegal to remove pages from their own platform that alter Facebook's appearance? As far as enforceability, that seems demonstrably false based on this post.

Um, I never said that anybody did anything illegal. In fact, that was the central point of my comment.

SF-guy can write his app, I can use it, and FB can delete his FB pages. No laws broken.

>They can write that in their terms & conditions all they like, but it doesn't make it legal or enforceable

That was In response to "It is against Facebook tos to create or use extensions that alter the experience".

When you say "that doesn't make it legal", does that not imply you think something is illegal....? Regardless, I see from your comment that you weren't talking about the page removal, but rather going on a tangent about the legality / enforceability of the ban on creating and using extensions that alter Facebook (as opposed to banning pages n Facebook that promote these extensions). We're on total agreement on that.

The pages don't do that.

If you use their website, especially if you build something on it, then you need to live by their rules.

Really? Tell that to AdBlock.
