had something similar to this happen
I had run a blockland server with alternative eval, so I could execute my stuff from titanpad,
been messing with a script for a while when someone starts using my console
and just types "poo" repeatedly, every 5 - 6 minutes
I had never sent my titanpad to anyone else before that and the console stuff wasn't found within it
so I did function serverCmdTalk(){}
and broke the function, nothing further happened
