Are people who put their Instagram name/handle on the window of their car attention seekers? Why do they do this?

yes they are

no they aren't

They want followers so they can get the “popular” seal. Same with youtube. People
get paid for that when popular. Paid by hits and when people watch full advertisements shown on their channel in between clips.

It's absolutely attention seeking. Question is it ONLY attention seeking? Or will they benefit in other ways like some sort of monetization.

Having a large following does have value. It's a low level of influence. Get enough eyes or attention as we say and a post might carry real world value to them and others
