She’ll know there’s more evidence because she’s put it all out there herself thinking nobody could touch her.
I myself have more but don’t want to upload certain footage/screenshots because it’s up to the young girl in question if she wants to pursue any retrospective action. She’s already had so much about her put out there when she was too young to consent to it, I would think long and hard about the merits of uploading potentially compromising content that might add to that for her sake.
I’d say Amelia will be seeking legal counsel, which isn’t unwise, but she must know deep down this won’t go in her favour.
