Really? Because every time a new dentist office, grocery store, etc. opens up I get unsolicited mail from them to let me know they're now a thing in my neighborhood.
Does it bother me? Not in the slightest. It's a community notice, and the Brave thing would only annoy me if it hit the levels that AOL CDs were at in the 90s.
This is probably a very location-dependent experience. I had literal stacks of spam mail every single mail day when I lived in Springfield and Kansas City, almost zero spam mail over entire years when I lived in smaller Missouri cities, and nowadays get maybe ~1-2 spam pamphlets per month at most here in Portland.
Probably based on a mix of local laws and/or how profitable each city is to market to.
I haven't done any of the extreme privacy things, but I do use a PO box for almost everything, and thus I really don't ever get anything addressed to my name sent to my actual residence.
