I think hiroyuki will do an okay job, regardless of if he sold data or not in the past, since moot is apparently buddies with him since a while ago I think it's more like, moot handed the site to him because he'd found someone who understood what he'd been through, and what he wanted for the site
Like I don't think moot was the best admin, but he wanted to keep 4chan alive and well and never went Jew on us since he never asked for donations (after donate or die anyway), never sold the site even though it was costing him money to keep it alive, never put on obnoxious ads or ads in obnoxious places, etc
He wouldn't have handed the site to someone he didn't think he could trust to keep it on life support at the very least
