Just one example of “who were these people pre 2018”

I’ve noticed that so many influencers, even niche influencers that I find chic, STILL deleted most if not all of their content pre 2018. I find it so weird that it’s like they have nothing to show for who they were, what their style was then, etc. idk just seems inauthentic. I just noticed this on Pia Mance’s profile—less than 200 posts, completely different person in 2020. Only 5 years ago…I’m all for glow ups but at what point is it…what’s the word I’m even looking for?
