The lack of info is likely because public service workers are assigned to places that house or assist children and the elderly. These are vulnerable individuals. Imagine if sasaengs (stalkers) got ahold of his work location and showed up there, then terrorized kids, or elderly who are suffering from dementia. If my family member had dementia and some whackos were hanging around outside where they're housed or getting treatment, I'd be terrified and infuriated.
Based on that, I don't think his public service is suspect. What's been bugging me is all the projects they've got going on while the guys are enlisted. They can't make money beyond what the military pays them while enlisted. So where is the money going from JH's documentary, the D-Day movie, Tae's recent songs, etc.? Escrow to be collected by them after they finish their service?
I was thinking more about why YG got the public service, and that "superstar day/regular guy day" crap that Hive released recently, mentions right on the guy day for YG that he gets physical therapy. Based on my research, stuff like physical therapy, or any intensive, regular medical treatment can earn someone public service or exempt them from service (like cancer for example).
NJ recently had a "day off". He's barely been in there and he's got a day off already. Jin has had zero days off until a couple days ago when he reportedly took a day off to see YG and send him off for his 3 week basic training. I'll give them serious credit, that's a dedicated friendship to drive 3 hours to see someone. I was not expecting that.
Armpits are BARELY talking about JH's documentary on twitter. Even hardcore fans are barely talking about it. Unfortunately, the dude just isn't that popular. You don't find people shouting "OMG I met JH!", for example. Something I've noticed is I see tons of fanart of the other members all the time, even of NJ who is only slightly more popular than JH. In the past few months, I've seen one fanart of JH by himself. The rest has been JH with other members, or retweets of old art. Even hardcore fans don't particularly like him, and I'm sure it has to do with his behavior. He is too much. Just watching a video of him is exhausting. He's also a tad gross. There's just something about his mannerisms that scream "creep", like he's insanely hypersexual, and while many fans won't admit it, I'm sure they are made uncomfortable by him.
