having a confirmed signature would (probably?) raise the suspicion tenfold

Not at all.

The question Is, by whom Is the signature confirmed? Anyone could've signed, even the carrier driver - which I've witnessed countless times. The purpose of using a fake signature, Is to release yourself as the recipient. And faking It, does exactly that.

like i said ive never done this so im just trying to be as cautious as possible

It's understandable.

Feel free to ask questions as needed.
