Buying Subs?

[amyfalafalagain]

Never posted in this section of the site before. Im trying to wrap my head around Social Blade. A huge family-youtuber Amy Maryon is someone my friend watches. She is in the dark/denial about youtubers being paid. She has a village of her own children so she relates to this woman. Anyway, I wanted to know from you experts what does this mean? Does this mean Amy is buying subs every single day? Im not too familiar, only learned from what Griffiths extended family has done, and discussed in their threads over the years.
Thanks in advance.
