@belghast My understanding is that Maxroll bulk trading is not another Discord. It's a website you log into with your PoE account. You load up your stash through the API, check the items you want to sell, then decide what price multiplier you want to apply to what shows on poe.ninja. Click Sell, and your items are now searchable.
I liquidated a lot of corpses this way. Hopefully critical mass of larger content creator audiences will make the tool a stronger option than TFT.
