I've just enabled CComments in my JEvents. I've created one comment here:
http://www.homebrewmap.com/index.php?option=com_jevents&task=icalrepeat.detail&evid=28&Itemid=449&year=2015&month=09&day=26&title=maly-machovsky-pivni-kost&lang=en
But it is displayed in detail page of all other events as well (there are currently only 3 events in my calendar):
