I respect that's your personal preference so I won't try to change your mind, but if you don't mind me asking... what difference does it make? :O If you're going out of your way to get an item from someone else that you can't get yourself, you're already at the step of doing so. Why does it matter if the item is from a TTer?A lot of people like myself don't realize the other is a TTer. Selling things or turnips prices that you TTd for should be marked with a big ol stamp saying so. That way we know if we're buying quality instead of (whatever the cool kids are calling TTers nowadays)
This is why I barely buy online anymore. Never know what item has been TTed to obtain
I 100% understand not wanting items that are hacked or otherwise, but items received sooner from TTing are nowhere on that level and put your game at no risk
