Magnetars and many of the magnetar-related objects are summarized togetherand discussed. It is shown that there is an abuse of language in the use of"magnetar". Anomalous X-ray pulsars and soft gamma-ray repeaters are well-knownmagnetar candidates. The current so called anti-magnetar (for central compactobjects), accreting magnetar (for superslow X-ray pulsars in high mass X-raybinaries), and millisecond magnetar (for the central engine of some gamma-raybursts), they may not be real magnetars in present understandings. Theirobservational behaviors are not caused by the magnetic energy. Many of them arejust neutron stars with strong surface dipole field. A neutron star plus strongdipole field is not a magnetar. The characteristic parameters of the neutronstars for the central engine of some gamma-ray bursts are atypical from theneutron stars in the Galaxy. Possible signature of magnetic activities inaccreting systems are discussed, including repeated bursts and a hard X-raytail. China's future hard X-ray modulation telescope may contribute to findingsome magnetic activities in accreting neutron star systems.

Central compact objects, superslow X-ray pulsars, gamma-ray bursts: do they have anything to do with magnetars?
