Am I wrong to be annoyed?

I took some shots of my Alma Mater’s high school spring football game. I’m not charging anything for the pictures, (as I was doing it to launch my sports photography socials, and i’m a small creator right now) and I gave everybody a link to go download pictures that have a tiny watermark. I posted multiple times about being tagged in any posts that use my pictures.

There were like… 5 accounts that I found that didn’t tag me but used exclusively MY photos.

I know I can’t MAKE them do anything, but I am slightly (VERY) annoyed, because i’m trying to be able to leave all my “schedule jobs” and go full time photography.
