  Accelerating black holes have been widely studied in the context of black
hole thermodynamics, holographic gravity theories, and in the description of
black holes at the center of galaxies. As a fundamental assumption to ensure
spacetime causality, we investigated the weak cosmic censorship conjecture
(WCCC) in the accelerating Reissner-Nordstr\"{o}m-Anti-de Sitter (RN-AdS)
spacetime through the scattering of a charged field and the absorption of a
charged particle. For the scattering of a charged scalar field, both
near-extremal and extremal accelerating RN-AdS black holes cannot be
overcharged, thereby upholding the validity of the WCCC. In the case of the
absorption of a test charged particle, the results demonstrate that the event
horizon of the extremal accelerating RN-AdS black hole cannot be destroyed,
while the event horizon of the near-extremal black hole can be overcharged if
the test particle satisfies certain conditions. The above results suggest that,
in the case of test particles, second-order effects like self-force and
self-energy should be further considered.
