The post included the business addresses of likely targets of retribution, including Comedy Central and Parker and Stone's production company. Chesser threatened the South Park creators on a variety of other online platforms, including his blog and Twitter pages. Chesser wrote, "We have to warn Matt and Trey that what they are doing is stupid and they will probably wind up like Theo van Gogh if they do air this show."
