Would this be possible?

Would it be possible for someone to make multiple accounts that are like bots, that would only idle for items, which you could trade with, and you could get items? (basically a random item generator, but more complex?) I don't even know if that would operate, or even be undetectable.

it works fine, its just that idling kind of doesnt work any more

They changed idling in "An active solution to an idle threat" where you have to actually move and play to get drops. Its basically not worth getting vac banned for a few extra items every week, plus it's hard to code an intelligent bot that moves by itself
