Nonetheless, let me try to page them, ask if they've hear any development from your case.
What I concluded from their last communication here, I would say that further insistence on "solving" this case is futile, I think that they have concluded this investigation and will not consider it further.
It sounds like, they caught this user abusing vulnerability, which puts all his other activities under scrutiny. With this, all trust is broken and they no longer want to have dealings with him. It's just how it looks to me, and honestly, I do the same to someone who I've determined has tried to take advantage of me.
Thank you for your insight. Perhaps they shared the same sentiment and conclusion, thus their silence.
However, I personally think it'll be best if I make sure of it before drawing any conclusion myself and before I can safely mark the case with status that's best fit the situation based on these factors.
I've send them a DM yesterday. They're usually slow on weekend. So, there is not much we can do but wait.
