I think you're right that this is a very different case.
I'm sorry you were falsely accused and I'm sure it's not any help to you to hear that whoever reported their suspicions likely felt that a child was at risk and was just doing their job.
It usually is just a collection of things that raises suspicions but those suspicions have to be reported. That applies to any kind of child abuse, it's usually a collection of things that authorities have to go on rather than direct witnessed evidence.
With you, there was a collection of things presumably relating to just one DC. With LL there's a collection of things relating to over a dozen so more compelling evidence.
I'm sorry for your experience.
