So yell at madaxe_again for publishing proprietary stuff, not plagiarism.

The internal justice system made two errors, not zero. That's never okay, especially if it claims to be errorless ( shawn-furyan put it better than I did)

Would you be okay with getting a fine in the mail for having done something that is logically impossible to do (such as plagiarizing from yourself), regardless if you had to pay a different fine for a different issue or not?

EDIT: I can't answer to the post below, for some reason, thanks for the correction on self plagiarism!
