all toons are database linked i asume? so all items/creds gained, sold transfered become traceable data...
Sony were able to catch all credits in game to account by adding >= booleans into the banking or inventory script, i remember reading about it.

(Lag, pet hate of mine!)
Also on a note about lag! It was said once that, the animals left behind at nests which aren't killed should auto despawn after x amount of time!
I was on naboo the other night, out hunting, it was nearly imposible to find my nest with all the left over mobs from killed nests.
