Well, you must have offended the gods of computing science :-)

But there are other earthly possibilities as well:

1.
$ less /etc/inittab
...
# Default runlevel. The runlevels used are:
#   0 - halt (Do NOT set initdefault to this)
#   1 - Single user mode
#   2 - Multiuser, without NFS (The same as 3, if you do not have networking)
#   3 - Full multiuser mode
#   4 - unused
#   5 - X11
#   6 - reboot (Do NOT set initdefault to this)
# 
id:6:initdefault:   <===================================== ????

2.
$ less /etc/passwd 
...
yourid:x:500:500:YOURID:/home/yourid:/bin/bash <====== /usr/bin/reboot ????
...

3. you have been hacked or did it yourself ...
