I might be out of the loop as far as the dox goes, but if it hasn't been attempted, I think it'd be good to do an in-thread round-table on what we know. Afaik (the thread moves fast, even during a DoS) we have his name (David Ginder), a prior address, spouse, wedding photos, vague stuff in a pastebin, and some other possible photos of him. We still don't know much about his location or work in japan, and confirming/deboonking his death seems to be difficult regardless due to not being able to just call a jp police office and ask if the dude killed himself.
Also, about that pastebin, it brought up his irs trouble, and went a step further and implied he was being looked into. Someone else brought up that he was eager to get his no-momentum thread nuked from orbit, including using extortion. Could this be a bizarre, idiotic attempt to not only rally people against the site, but also try to dupe the irs? The story his buddy told was such an asspull, and byuu made two llc's due to tax concerns (afaik), could ducking the taxman be a motive?
