These definitions from Robin Sloan are helpful:

An accurate definition of “influencer” is: a virtuoso of a particular internet platform; someone who has learned to use its mechanisms to achieve their own objectives, rather than the other way around.

An accurate definition of an internet “creator” would have to be: someone whose income is determined by a platform’s algorithms.

Aligns with why platforms suddenly started talking about the “creator economy” instead of just influencers.
