I might be able to overwrite the saving to not call if your not an admin if I knew the function, but as Ephi said if its done clientside I probably wouldnt be able to.
Use a brick generator and use alot of custom bricks.(what I try to do, along with using a private color set)
Otherwise, just put your name everywhere. I suggest writing it backwards somewhere in a way that they wouldn't take it out.
I.E. have a tv thats showing a show called aduc on channel 007
Or make a sign and have a secret path to the back of the sign and have the back say your name.
