I just don't even understand the vengeful response.
If someone reported me to SS, knowing it would be utterly unfounded, I'd be angry that I had to waste my and their time yes, and If I knew the reporter and felt it was malicious/harassment I would log it with the police. But I'd just think it was pathetic and laughable and rise above it not wasting any more of my time and energy over it beyond that. If I actually thought someone had got the wrong end of the stick and had genuine concerns, I'd be embarrassed, concerned and address it what I had done to create the concern. The SS investigation would show that it was nonsense and that would be enough.
It's like she'd been caught out and was fighting back, rather than looking at her own behaviour, blaming everyone else, being clever and thinking she was some kind of master detective. I can never imagine her saying, "I was wrong", just doubling down.
