He violated the Terms of Service and caused problems. At the end of the day if he's going to be a nuisance to everyone and put himself at risk on the internet openly then he neither realizes the situations he could put himself into or understand how anyone reasonable will feel about it. And he should be lucky that someone more disingenuous isn't trying to fuck with him, that'd be worse than us harping on him to stop communicating with any of us or others.
At this point, it's better to put the situation to rest and move on. It no longer concerns any of us what he does.
