The 22-year-old rugby star had nude photos leaked through an online sex forum by several male users in November 2017.
"Here's what I've got," an unidentified man from Amsterdam wrote while uploading eight images of Charlie to the porn website.
When another forum user asked the source of the sensitive material, a man from Durham, UK, responded: "Somebody catfished him."
"Catfishing" is where a person adopts a false persona online in order to deceive and manipulate people.
