My friend is moving, and he suggested I could use his house as a drop. He moved out about 4-5 days ago, and I was thinking if it's safe to use it since it might take the post office a while to catch on, since they're a bit slow. Would this be a horrible idea or should I go for it while I have somewhat of a chance?
This is extremely risky. While you may get away with it for a bit it really isn't worth the very real chance you'll get caught. Horrible OpSec move in my opionion.
