I'd really like to delete a large number of friends (~400) from my Facebook network and I'd really like to optimize this process.

I found a greasemonkey script that will apparently help here: http://userscripts.org/scripts/show/160224

However I'm hesitant to use it since I don't understand the source code (dont know js) and I have no way of telling weather it is malware.

My questions are:

  1. Does someone know how to remove many friends at once from Facebook?
  2. Has someone tried this particular greasemonkey script? did it work?
  3. If someone has time, and js experience, could you tell me if there is anything malicious in the source code?

Thanks

This question came from our site for computer enthusiasts and power users.

    
Your first question is off-topic for SU (on-topic for webapps.SE though). Also, if you don't trust the stranger who wrote the script, why would you trust another to vet it for you? –  Karan Apr 5 '13 at 22:37

Well, I'd like to think that a crowdsourced opinion is better since I believe most people to be good. Also, they have less incentive because they would not benefit from whatever harm may come my way (such as stealing my information). –  kamula Apr 5 '13 at 22:44
    
Remember that if you're simply polling for opinion the question is likely to be closed as being "not constructive". –  Karan Apr 5 '13 at 22:49
    
If you have that many people to remove, how many will be left. Would it be easier to just create a new account? –  Hennes Apr 5 '13 at 23:35

I'm not the developer of that script (Really! Honestly! Truuuust me!), but looking it over, it does not appear to be malware. For instance you see no XHR or GM_xmlhttpRequest requests to third-party servers. It has no obvious attempts at hackery.

As for doing what it says it will, It looks like it should, and with a nice mechanism to select and confirm those friends to remove. I have no intention of testing the script.

It's always a good idea to backup your FB friends, for peace of mind, if nothing else.
