Fast decline trades when you get a bunch of spam offers you would never even consider when you post a card. It’s very annoying to go through offers and click view and wait to load and then reject and then bring you back to the trading activity menu.
It would be nice if we could add a swipe right feature to decline trades (maybe with one confirmation menu saying like are u sure or not even a confirmation screen). But don’t add one to fast accept because while it might be useful for mass trades that you like, you don’t want to accidentally swipe and accept a horrible trade.
