Follow/Unfollow all members of a Star Citizen organization.

StarCitizen_FollowOrg.js

/**
 * @author nitzel
 * @desc A simple script to follow/unfollow all members of a organization
 * in Star Citizen. To use it just
 * 1. log in on https://robertsspaceindustries.com
 * 2. Find out the SID(Spectrum ID/handle) of your organization
 * 2. Open the javascript console (Chrome: F12, ESC toggles it)
 * 3. Paste this whole script and press <ENTER>
 * 4. To   follow all: changeOrgFollow('SID', true)
 *    To unfollow all: changeOrgFollow('SID', false)
 * 5. Wait till done
 * 6. When sharing, please refer to this website ( https://gist.github.com/nitzel/590a97ecbdb2c8256fff )
 *
 * Example: For "ACES HIGH ~ UP WITH THE IRONS!" the SID would be "ACESHI".
 * We want to follow the members, so we say true. To unfollow it would be false.
 * > changeOrgFollow("ACESHI", true);
 *
 * There are a few messages that can come up, you can usually ignore them.
 * OK -> it worked :)
 * Validation failed -> You already follow this player.
 * ErrCannotAddItself -> You cannot follow yourself.
 * ErrContactRelationNotFound -> You cannot unfollow s.o. you do not follow.

Updated the POST's content type to JSON. API stopped defaulting to it.
Nota bene: this script just adds user after user. You'll see warning messages when it fails to do so as it reaches the 250 contacts limit imposed by RSI. Ignore them or change the script to stop after 250 users 👍
