This was DFB's old Reddit profile, screenshot comes from a Wayback Machine capture from June 17, 2022. I assume he deleted it when Skibidi Toilet was already a thing.
No idea what was the reason behind the deletion.
However, due to the fact he officially named the Red Suited LCM "Fred" and the Core Hijacker "Corefucker", I assume he IS active on Reddit, more specifically the Skibidi Toilet sub, possibly under a different username (Imagine if he's actually pretending to be a normal ST fan there)
