The ESTA form asks for social media accounts (though not passwords, and ostensibly providing the accounts is "optional"): https://esta.cbp.dhs.gov/esta/

Oh wow that wasn't there last time I ESTA'd. Good thing I got that business visa a few years ago.

Then again, I used my social media and general web presence as partial justification for the current O-1 visa so ... oh well.

At least they can't find anything by googling my legal name.

Fucking hell, that's the first time I see this too. I might have to reconsider my US trip...
