  A well-known property of quantum nonlocality is monogamy. However, recent
research by Silva \emph{et al.} shows that multiple observers can share the
nonlocality by using weak measurements [Phys. Rev. Lett. 114, 250401 (2015)].
There is an open question left in their result: whether the nonlocality of a
single particle from an entangled pair can be shared among more than two
observers that act sequentially and independently of each other? In this work,
we analytical and numerical shows that it is possible to observe a triple
violation of CHSH inequality between Alice and three Bobs when the measurements
of each of the several observers at one side are unbiased with respect to the
previous observers. This result overturns the conclusions and proofs of
previous related work on this issue which has been widely shared in the
scientific community before.
