Dean has made threats against people in the past, although he's gotten more subtle lately. He's been well known throughout the autism community for years, perhaps more like decades, I don't know. There are reasons he's banned from practically everywhere. Real, serious reasons beyond the usual reasons people are banned from places, although he will claim there are not. Mods can PM me if they want details.
In the meantime, members, especially children or anyone experiencing emotional problems, should be more careful than usual not to give out their address, phone number, etc.
