Humour must be used carefully, if at all. What might be funny to us might not seem funny to a new and frustrated user with a problem.
Study the CCN user agreement, by using the 'g' shortcut command 'g agreement'. Avoid giving an answer which may suggest violation of user policy.
If someone sends a message to Userhelp asking how to beat the system, please do not guess or give your personal opinion. It may not support the user agreement re: policy. If you are not sure, please say so, then point them to the user agreement.
