The index and the follower count point at different people. Of the thirteen accounts above 100,000 followers, five grade B, while the highest score on the page belongs to Beca Jover and three of the eight A+ grades sit under 100,000 followers. Size is not what the grade is measuring.
Local reach splits the roster. The Spanish audience share runs from 20% to 90% with a median of 63.5%: twelve accounts hold 60% or more, and six sit under half, including two of the three biggest followings. A Spain-only campaign starts from that bar, not from the follower number.
The roster is drawn, not performed. Nine of the twenty name illustration or drawing in their own bio, and three more work behind a camera, one of them freelancing for Getty Images. There is one art historian and one graphic designer. Five bios sell directly, through an online shop or commissions taken by DM or email, and four name a published book.
