[Penguin]

I have been told that your base was built on top of someone else's and had to be removed. In addition to this, you had actually broken into the other base and altered it, counting as grief. In light of this, can you please answer the following questions as well:

When is it ok to alter other people's builds?

If you discover that you have built within 100 blocks of another player, what should you do?

If a build seems abandoned or is owned by a banned player, are you allowed to modify it? Explain your answer.
