Of course it is not wrong. It serves as a warning to other people.
Not like you, using flash just for your photo. You ask any any
other people whether flash is the correct thing to be done when you
night shot.
nothing to say liao change statement hor?
i
love this...from my photo is useless and I'm an idiotic n00b who
doesn't know how to take nor appreiciate photos to this...nice
"warning" btw...doesn't sound like a "warning" nor "advice" to me
from the start, but instant flaming. As I've said, please go
improve your EQ and reflect on your own actions...and quit
boasting, because it brings you nowhere 
Just FYI, I've tried taking non flash shots a million times in
horrible lighting conditions and the photo always turns out
horrible despite "professional" claims that it'll be good. Do you
think I've never experimented with my camera before? Especially
since its been with me for 6 years?
Stop PRETENDING to be
a genius/professional when you're not.
Now going to find a point to flame my old camera is it?
HAHAHAHAHA.
