I the real world, you can file criminal complaints anonymously and engage a lawyer to enforce a damage compensation through civil court proceeding!

You obviously live in a different world than the rest of us (I mean, even more obviously than it was already). In our world, you
can't file a court case anonymously without the approval of the judge, which is only granted in extraordinary circumstances, what with the whole "right of the accused to know their accuser" thing. Human rights are so inconvenient like that.
