I agree with this! The registrar should not have triggered a suspension because of this. They're not obligated to, and the two processes should be decoupled.
No.
The source should be more careful. It's the equivalent of a renowned newspaper printing warning a restaurant being unsafe to visit. Should the customers' willingness to visit be magically decoupled from this opinion?
I'm not saying they should "ignore" reports of abuse but treat them as they are -- reports. They can then perform their own independent investigation.
That may well have happened here. I suspect the author isn't telling us something.
