What happens if someone is banned from both companies (even for a very legitimate reason such as hosting illegal content -- they still need to access government services)?

What about people hosting content that is illegal in the US but not Germany (not sure what that may be now, but with the direction the US is taking maybe in a couple years even the fat Vance meme could become some kind of illegal subversive content). Anger the big daddy and your identitiy is gone.
