On the other hand, if I actually have a sign indicates that some secret event have not happened, how can I remove that sign if I truely believe I don't wanna keep telling the world that it have not happened? If I remove the sign just because I no longer want to keep the sign up and someone takes it to mean that the secret event did happen, when it really didn't happen, do they have ground to sue me for fraud or lying?
