Asking this hypothetically as I have not burned an address yet. But say I have a package that never arrives or is seized by LE. Is it ever safe to ship to another address under my name? Why or why not? What's the next step if I get burned when it comes to ordering again?
You could certainy still use the dnms. Your house+name combo would probably most definitely may be watched for the remainder of technology. Shipping to another address should be a bit more difficult to grab unless the vendor has horrendous stealth. Would probably want to wait a while before using your name on a new address though.
Next step would be upping your opsec, researching vendor stealth, even asking vendors for specific stealth you choose (ie requesting vendor pick up some nike shoes from some random mall and sending your pack in them or something).
