Important question: what social media is Elias using? The amount of personal information people are putting on the internet is something catching an eye of any Eyevatar.
Anyway I think he has facebook and he added to his friends list every single employe of the Magnus instute no matter how much private or in secret their facebook is. He keeps randomly asking them why haven’t they accept his friend request until they do. He also force those who doesn’t have an account to create one.
He also made them all join some group where he keeps posting announcement, bad memes and bad motivation quotes. He use lots of emojis mostly incorrectly.
However I will leave up to you to decide whether he keeps doing all those boomer stuff just to be obnoxious or because he really doesn’t have such a good grasp on modern technology as he would like to think…
