Sell Items On Trader directly from Bank

[SteveCampsOut]

So some chracter on Facebook Elderscrolls Online group is claiming he's been selling items on guild traders for over a year directly from his bank. I've been playing since beta and this hasn't been an option since the big Duping scandal waaaay back in the day, and they stopped allowing people to sell items from their bank. Is there some new addon that allows this again, or is this guy delusional or lying?
