Tnt was and still is the most important griefing tool out there. With the redstone update it made this possibility even worse. What most of you probobly think is when you here tnt go off you have a water bucket to put it out. Well thanks to the redstone update that is now imposible. With tnt minecarts it is now possible to blow up tnt without sound. It blows up asp. As in as soon as they pull the lever asp. There are two ways they can do it. Way one, if you build a ramp of powered rail if you put two or more tnt carts on it when the top one hits the bottom one of the ramp when the rail is activated. BOOM. A explosion happens right then. It is also able to blow up other tnt by it getting activated when it rolls over a activater rail when it is redstone active it blows up. Way two comes right off of that. If you have more thsn one activater rails next to each other then BAAM. When it rolls over one it lights without a sound, when it rolls over the second BLAAM. Watch out fellow map mackers like me cause the griefing world has gained a new superpower!
