Cheers JohnK! - It would be nice if administrators had more "powers" against trolling - as in, a system too remove stockpiles full of tailings, and powers too see who placed certain items. Thanks - keep up the good work, John!
Your on the right track... A stock pile is better, you can store EVEN more tailings in 1 area. You need too dig deep, bellow soil level, you need a at least 5x5x5 area of NONE broken stone, top, bottom and walls
Keep tailings underground, not touching any dirt in a solid never pickaxes stone box - too remove the mess caused by tailings... It shall slowly disappear over a certain time period. some trees and plants shall never recover the green colour though
