When it comes to things related to official iDOLM@STER merchandise, nobody should really worry about importing anything. There is really so little objectionable from a glance with any of the material. At most it's stuff like
this or even
this that comes through, and I'd hardly consider that pornographic. All of the G4U packages have fairly tasteful representations on them so far. G4U is fairly tame all things considered, as it's what the user decides to do with the game that could call any inappropriateness to the table. That's for the user to decide, as I could care less what someone does with their own copy.
Doujinshi I suppose might need careful consideration, though I've had little issue with importing any thus far. I use a deputy service to order from Toranoana on occasion. They tend to include the catalogs that come with the orders. One's a general audience catalog, another is a BL catalog (despite... not ordering anything of the sort myself), and the last is an adult oriented catalog. No packaging, they just plop it on top of whatever's in the box. It only displays covers for the
variety of manga and doujin material they sell, but those can be explicit enough on their own. I've not had any issues so far, and I don't particularly anticipate them either.
The postmaster in this town is a good friend, and she's been in the business for thirty-odd years. I asked her about it once upon a time and she assured me that unless the content is mostly driven at a specific controversial (or illegal) concept? Then you should be A-OK. These folks that search mail have superiors to report to. Their superiors have others above them to report to. The entire chain has to agree to escalate the issue at each juncture before any action can proceed at the top. I worked for the federal government for seven years myself at the IRS, it was a nightmare gettin' anything done. Now I'm associated at the state level as a foster care provider... still it's a nightmare gettin' anything done.
Try not to worry so much about it when it comes to iM@S. It's all good, so you should enjoy it.
I won't comment on that Handley case or the fella himself, it's not for me to say since I don't know him personally.
