The videos are a joke to bring attention to an issue Jagex has neglected for over a year. I know this has nothing to do with you as you're just returning to Jagex, but for over a year I've read the new section as hundreds, if not thousands of login attempt posts and tweets are buried and ignored. This has been extremely frustrating, especially when you see public figures exclusively offered support to change their login usernames (but only if they're deemed worthy by Jagex).
That's why the videos also bring attention to the fact that getting customer support is practically impossible, unless you're a content creator. Then, it becomes easily accessible with access to the creator discord and open DMs to jmods. The videos are satirical, to raise awareness for those who've been ignored because they don't have a high subscriber count.
