  If radiative and self-force effects are neglected, we find that feeding a
test particle into a near-extremal Kerr-Newman-AdS black hole could lead to
destroy their event horizon, giving rise to naked singularities. Hence
radiative and self-force effects must be taken into account to further test
cosmic censorship. Moreover, the allowed parameter range for this test particle
is very narrow, this leaves the possibility of radiative and self-force effects
considerations to cure the problem of WCC violation in Kerr-Newman-AdS
spacetime.
