The website also says:

"Australian research shows that 99% of domestic violence cases now involve some form of technology-facilitated abuse."

Where the "Australian research" is linked to a page where the first Key Finding states:

"Over one quarter (27%) of domestic violence cases involve technology-facilitated abuse of children."

Doesn't fill me with confidence in anything they say (even if I do believe the advice is right).

The relevant quote* from the linked Australian research is:

  Technology-facilitated abuse is becoming more and more of a key feature of domestic and family violence. A 2015 survey of 546 domestic and family violence frontline workers found that 98% of respondents had clients who had experienced technology-facilitated abuse.

Can you expand on what it is that "Doesn't fill [you] with confidence" ?
