How to leave a facebook network

*** EDITED: Unfortunately this solution does not seem to work at this stage as facebook seems to have changed their code to prevent people from being removed from their primary network. I encourage you to report this to them by filling out this form and they might eventually do it for you: http://www.facebook.com/help/contact.php?show_form=profile_bug. As a workaround, you may choose a different network, that you are ok to keep, then you can remove your old network. If anyone reading this has a solution, please feel free to comment below. I'm however keeping the original post for the sake of history tracking. ***

I might be an exception, but it did disturb me a lot to have the name of a network added under my name in facebook when looking in friend lists, such as my friend's friend list, or when you open the link of the list of people who liked a post... etc. You might just want to get rid of your primary network for other reasons (one of the simplest, not part of it anymore), but to be honest, when I tried to remove this annoying network name from below my name, I did not find a solution up until today.

Not sure how it was before, but today if you have only one network, that one has to be your primary, no matter what. Once you made a network your primary, for some odd reason, you cannot leave that anymore; the 'Leave network' button that was there before you made your network primary simply disappears, even from the code behind apparently.

After some time searching for it, giving up and then just really wanting to find a solution, I finally stumbled upon an excellent post from Varenya Mehta VM that did not address my issue directly but had the solution to my issue in it too. The post addresses Facebook's "You are already a member of this network" Bug, however going through it up until point 6 then applying the javascript solution, I could actually leave my primary network on facebook.

Important note: I could only use the javascript solution (update #2 of the above post) as I do not use Firefox but Chrome instead. This solution only worked for me if adding the javascript into the console of Chrome's Developer Tool (and not in the address line, as the above post suggests).

I know it might not be easy for less technically savvy people to apply the solution, so feel free to AskMe if you have questions, I'm happy to help you out!
