A tag is just a named reference to a particular commit (or other object indeed). Once you set a tag, it doesn't move (unless you override it explicitely).

You can't prevent people from commiting something. It won't move the tag, but it will create a new commit whose parent is the tagged commit.

A branch is also a named reference to a commit, but the difference is that when you commit, the current branch is updated (i.e. the reference points to the new commit).
