Rescinding?

So this has been bugging me for a bit now and I was wondering if this has any possibility of my college admission being taken. There is/was a group chat for the freshman of the school I would be going to and a picture icon someone uploaded looked like someone wearing a shirt with the logo on it but on further inspection was them pouring from a alcohol bottle into a cup. I would not have joined this specific group to begin with had I known about this being the image people first saw when they joined the group chat and left the group immediately when someone pointed it out. The thing that’s been bugging me is that they ( the person who mentioned the picture) said “I can’t wait for admissions to see it.” ( like they were going to report it) Am I overreacting about this or should I email the school and explain the situation since I did send some messages (nothing bad, just answering questions about WUE and talking about graduations) or ignore it?

“Am I overreacting ?”

Will the sun rise tomorrow?

^ Yes, agree with @T26E4 You are way overreacting.
