Josh of all people would know better than to use his real address for literally anything.
A e commerce account that could be breached and data dumped. Something on his credit that someone pulls because they have access and don't care about consequences etc.
Look at the site he runs, he knows better.
So he likely has all utilities, credit accounts, packages etc sent to a remailer. Perhaps one close enough to go pick up a package or letters and that's what's being looked at: But they're also happy to scan to email, or FedEx you your mail too. So, you're right.
So a couple autists are bored and playing a game of capture the flag. Like HWNDU all over again. I'm not going to do anything with his ox even if I found him, If I sent him 20 pizzas he'd just think it's the 20 he just ordered for himself.
I
would be nuts enough to do something like move down there for a month or three and apply for all four major carriers though.

Maybe not in Josh's case. But definitely for someone who actually did something to piss me off besides just being a cunt on a forum.
