Apparently the app (written by a former NSA guy) is normally used by evangelicals and conservative Catholics to help break “porn addiction” by allowing a family member or pastor to receive screenshots, recorded every several seconds or so, of the “addicts” phone. This is to help with accountability.
In this case the husband I think is out on bail for alleged child porn. The family had to to agree to this monitoring on all devices including the kids or they wouldn’t allow bail.
From the article “he” supposedly violated his agreement when his wife’s device hit pornhubs servers.
The authors were able to show that chrome will hit servers for regularly loaded webpages without being specifically asked. The software also says it’s not supposed to be used for legal monitoring.
Of course the husband and family agreed to the monitoring of their own free will after he was threatened with remaining in jail without it.
