1) with the Parents on Instagram they can monitor more closely.yeah also you will noticed that Justin and Brooke have now joined Instagram, that other video they didnt showed maybe she actually did the sign and didnt had any explanation to the family ,
but also there views are down so maybe they did to get some clout. sabre said its her dream to be a YouTuber however in that video she says her dream job is to be a fashion designer that's quite weird
2) #internationalhelpsign its created as a secret gesture because you want to subtly use it and didn't Sabre just look so 'innocent' when they brought it to attention.
3) Dream Job - Sabre - Fashion Designer - Her family makes merch for kiddies. Where is she gunna get an education in Design?
In two years she is gunna vote, drive on her own, look for further education. That is if she qualifies under the quality of Home Schooling. The real world is gunna mess her up. She hasn't stepped out of her YT cocoon to learn anything from the school of Hard Knocks. She is gunna be in so much unprotected shock.
A great (sad) episode would be Sabre taking a leaving exam. Might help her realise how unprepared she really is.
