Early on I've made the mistake of sharing my solutions with people I knew. Unfortunately they kept sharing the solution too, and so on.
Two times I was pulled into a profs office after the relevant lecture, to be questioned about it.
After it became clear that I was the author, and what happened, nothing ever came of it (for me).
Ironically both times the copiers supposedly failed to remove the git repo that was part of the handoff, so it was primarily about verifying I was the original author.
Lesson learned: "invisible" watermarks work, because people are generally lazy (also don't share graded work, just offer to help)
