Posted Acceptance on Social Media -- would this affect future decisions?

I was admitted into my early action school (T5 Engineering) a while back. I was happy with it and planned to most likely enroll there, so I shared the good news of my acceptance on my public Instagram account in a post. However, I still wanted to hear back from the other colleges I’d applied to and wanted to see if any of them would be able to change my mind.

Was it possible college AOs went on my Instagram and saw this post and decided not to admit me because they think my yield would be much lower? Do AOs at top schools check the social media of all their applicants?

Very doubtful, and colleges are busy with other things right now.
