She won’t buy views as any sudden jump like that would show on her social blade as a big spike on certain days. Don’t pay too much attention to sub count / view count she’s done YouTube a long time most of her old subs are no longer active / people only sub for her Disney vlogs. Like / comment ratio to her view count seems accurate, also remember she’s probably deleted tens of comments that don’t meet her standards.
She has a very active Tattle, hundreds of different members and were just a small portion of her community - her IG and Twitter stats seem to match her YouTube stats also.
