  Magnetars and many of the magnetar-related objects are summarized together
and 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-known
magnetar candidates. The current so called anti-magnetar (for central compact
objects), accreting magnetar (for superslow X-ray pulsars in high mass X-ray
binaries), and millisecond magnetar (for the central engine of some gamma-ray
bursts), they may not be real magnetars in present understandings. Their
observational behaviors are not caused by the magnetic energy. Many of them are
just neutron stars with strong surface dipole field. A neutron star plus strong
dipole field is not a magnetar. The characteristic parameters of the neutron
stars for the central engine of some gamma-ray bursts are atypical from the
neutron stars in the Galaxy. Possible signature of magnetic activities in
accreting systems are discussed, including repeated bursts and a hard X-ray
tail. China's future hard X-ray modulation telescope may contribute to finding
some magnetic activities in accreting neutron star systems.
