No I didn't, with the few interactions I had he seems to be dismissive of what I am trying to say. Maybe I will try doing that if he didn't respond here.
It's probably safe to assume you didn't send Sato a pm regarding this thread then either, so I sent a pm to the user and asked them to have a look at this thread.
You did the next good thing which is what the OP ought to have done before going ahead to create this thread. This is one way to escalate a situation which could have been handled easily and quietly with a pm.. I don’t know where OP tend to have had a conversation with the user and found that, a pm would have been up to no good but then, users might be a lot more understanding and you can spill some details in the pm that you wouldn’t want to let out in the open. That’s why it’s a pm, except when it’s needed for some evidence to an escalated situation.
