When does a complaint become slander/ Companies' rights to be treated fairly

<p>I do read HelloPeter. I am wondering though? </p> <p> </p> <p>Does HelloPeter not have an obligation to determine whether a client has a genuine complaint?</p> <p> </p> <p>Is there not some onus restant upon HelloPeter (and any other such site) to ensure that they are not just attacked by malicious "clients"?</p> <p> </p> <p>What sort of recourse do companies have (other than the HelloPeter subscription-self-servingat best) to respond?</p> <p> </p> <p>Is this not corporate tyranny, very much like a dicatorship?</p> <p> </p> <p>HelloPeter</p>
