To prevent cheating (like copyin

Answer 1

You can prevent the user from actually selecting the text so it can not be copied - however I'd still combine this with paste detection as others recommended

.noselect {
    -moz-user-select: none;
    -webkit-user-select: none;
    -ms-user-select: none;
    user-select: none;
}

this can be selected
this can NOT be selected

But the user can still open the page source and copy it from there.
