I tested with following css:

.wpdiscuz-comment-message {
display: none !important;
}

#wpdiscuz-comment-message.wpdiscuz-comment-message-auth{
display: none !important;
}

@thl,

Use the CSS code below: 

.property-detail-main div#wpdiscuz-comment-message {
   border:none !important;
   padding: 0 !important;
}

Put the code in the Top Admin Bar > Customize > Additional CSS > "Additional CSS" textarea, save it, delete all caches and check again. 

Cool! it works. 

thank you so much
