Recently I've Been Playing On My Favorite Game Mode Called Destroy The Monument, I Was Shocked To See How Many Team Spleefers/Abusers What Ever You Would Like To Call Them Destroyed Blocks Under Me On A Map Where I Was Trying To Mine Diamonds.... I Think The Staff Team Should Moderate Those Servers Please <3 Thank You. -Shuffler4life
Staff has been monitoring but it's hard to catch them all. Please use the /report function when you see it going on. If staff for that server are on another server they'll see it.
In that case, your best bet is to screen shot it and post it here on the forums but I'm sure /report works as I've seen many come through myself.
