This sounds like you mean success or recognition are states in perpetua. Once you’ve arrived you can never be forgotten.
IMHO Instagram is a great place to test new directions, get feedback on what works what needs tweaking. Or it’s a place where a photographer can let his or her hair down. Follow Stephen Shore there or Steve McCurry, Dotan Saguy to see how established photographers use IG to stay relevant or keep a thumb on the pulse of the public.
And If a prospective client asks a photographer for their IG, s/he says, don’t have one?
