Now that I think about it, there's a real possibility this might be ProJared.
Anon here is demanding you swear to secrecy, which is a personality trait of ProJared's, given that he tried to make his own wife sign an NDA.
Anon is pushy with his secrecy demands, which might indicate that the emailer is desperate to save their face somehow, which I imagine is a PJ mannerism at this point.
Anon gives off a vibe of an insanely overinflated ego, which if anyone has seen Projared's thumbnails on his main channel, ALL of his video banners feature his smug image of him looking all greasy and spergy.
And lastly, anon used the report function, which is a trademark tactic of SJW cancel culture.
Is this too big brained to consider?
