Our policy on this matter does not require the TLD operator to exert any 
control about what happens at the "third level" or below. So any TLD 
operator who is concerned about that can un-concern themselves. :-)

(Firefox also includes a character blacklist of those character which 
look most like protocol chars (slash, dot etc.). This helps to prevent 
confusion about the level of a particular label.)
