We have No Banned items, We Limit some, but only ones that NEED limiting, all Griefing items are unbanned [because griefing is fun. :) We at FreeRealm know that!] BUT there is also nPVP [where you first spawn] that Is NOT grief allowed, Griefing there will result in a Ban.
do /warp pvp or click the sign at spawn.
Thanks, and Welcome back. :)
