Air carrier dispatcher reports a flight crew accepting an ATC reroute through weather he had flight planned to avoid and doing so against his specific advice.

Narrative:

Flight was planned on a route to avoid an active SIGMET area with thunderstorm tops to FL450. During taxi crew advised me that they had received a re-route. I plotted the re-route on flight explorer and it went through the area of weather I planned to avoid. I advised crew not to accept the reroute due to severe weather along the route. I further advised the crew to request original filed route. On the map display; I observed the flight became airborne and they had accepted the ATC assigned re-a route that would take the flight into unsafe conditions. Furthermore; the crew did not communicate their decision to disregard my safety warning. Subsequent contact efforts by the relieving dispatcher were also ignored. Lack of communication with the dispatcher; as well as accepting ATC re-routes without dispatcher consent are becoming more commonplace.
