Well, he's underage, but, in addition to that, he became a victim of grooming by the fact that he's been chronically addicted to websites like the Shlog, so, in my opinion, it was more moral to keep him out than to let him keep wasting away on our site.
I personally gave him spiritual counseling a few weeks ago after Soyteen Liker (the Hispanic former pooner) contacted me about him requesting my advice (as she had contact with him via Discord DMs), which I gladly gave him (he mainly just had religious questions regarding God's forgiveness, but he also asked some stuff about confidence and how to start recovering from his internet addiction). During that contact, he seemed to accept that it was better for him to stay away from the Shlog, rather than try and return in the future, so I'd say it was the better option to ban him, for the sake of his own mental stability (his personal situation made me cry for a few minutes on the night that I gave him all of that advice because of how mentally torturous it sounded as I read his messages; that's how bad things have been for him, and I don't want him to fuel that internet addiction any further).
