>>40726259The entity you're talking about is called a "janny", and it's a mythical creature that occasionally shows up in disguise to observe the humans it lives alongside. When the janny decides it doesn't like what the humans are talking about, it casts a spell that erases any physical record of the conversation they just had. Nobody knows why, and it's widely assumed that jannies simply delete whichever threads they feel like deleting, whenever they feel like deleting them.
