Just today, someone was spawning zombies at spawn and i was accused of spawning them by a mod (even though I didn't) I believe that there should be a message that comes up on any mod's screen saying "[playername] spawned [number] [mob]". As all $100 donors know that spawning mobs at /warp [anything] is ban worthy, only about 1/10 players would spawn them. This can also save many innocent donor's behinds!
