Alas, every mail scanning service I could find required prospective customers to already have an address. Unless you have recommendations?

I fear I'll have to contend with this assumption no matter what I say.

However, I may as well reply regardless: I am planning nothing illegal. That's the point of going to all this trouble. If I was willing to provide a fictitious address to commercial mail scanners, I would simply do that, instead of offering a quarter-bitcoin to a stranger to rifle through my letters.
