Hi,
 Many Thanks for all comments.
 The case I meant was exactly the 2nd one. Customer has an old connectivity
to LIR-1 and have got a new connection from LIR-2.

 That's the case.

  In this case, what should people at LIR-1 Do? Can they ask LIR-2 people
to stop forcing customers? 
  And if the answer is positive, What's the rule, if LIR-2 people continue
to behave like that?

 I agree. Another possiblity is that LIR-2's people are trying to fulfill
their own test period ( according to RIPE NCC slow starting ) and
somehow attack to LIR-1 reputation.
