Houses change ownership, people make mistakes.
But the real reason you shouldn't do it is that you don't actually get any deniability. John Doe who used to live at my address is not going to order drugs and ship them to my address. Especially if he's moved any reasonable distance, or is dead, or incarcerated, etc. It's no less obvious than just shipping them to yourself.
That was three or four years ago and I've had a PO Box ever since. So I thought my neighbors on nextdoor were exaggerating and then I was forced to have a package delivered because Google uses FedEx Ground for their slowest and cheapest option.
It was less than an hour between email notification of package delivery and my checking to find it gone. So add some buffer time in case the driver was slow to update the package status but still I'd say an hour to an an hour and a half was rotten luck or people are actively searching for packages. Probably both to be honest. I'm sure there's lots of confirmation bias there.
(Yes I follow the recommended process for dealing with it.)

" It's my address but someone else's name
We deliver to addresses rather than names so our advice here would be to put a cross through the address and write on the item 'Not known at this address' or, 'No longer lives here' and post the item at your convenience - you won't need to apply any postage. Where applicable we will return the item to the sender hopefully allowing them to update their records. "
After we started doing this we got a couple of letters from the likes of Zurich Ltd addressed "to the householder" explaining that they'd love to stop sending us junk, but they have to, and if we could give them any details about where the old residents might be, that would be great. I wished them luck and told them the best we knew they'd moved abroad, permanently, possibly to Turkey.
Also postman doesnt give a fuck.
Edit: reason I wrote that, is that I remember one time, some dude found weed on the street, and since he didn't smoke he gave it to hit friend. So the same here. (But it's a joke cause mail+drugs+address+police no bueno)
