Is file diving allowed? File diving is just opening up the game's folder and then searching for stuff in the files, not modyfing, opening (altough we know this is allowed) or (neccessairly) publishing them. I wasn't pretty sure and I don't remember the ToS say anything about it.
Pretty dang sure you're allowed to peek in there. OOO can't really tell who does and who doesn't, regardless. No point in having a rule against something that can hardly be proven.
