I cannot make any assumptions about how people will use the tool. That is why it is important to seriously examine the issue and to have very clear directives and guidelines. People need to understand that the tool must not be used to communicate with the public or even to communicate with other people within the public service.
However, as it has been said many times, this is a comprehension tool. If that is what it is used for and if there are clearly defined and well established guidelines, then I think that excessive use could be prevented.
