It is sometimes irritating to see the same exact thread posted across several different forums (and regardless of the user name, if the OP is exactly the same, it's pretty conclusive the person is the same person), it is also instructive at the same time.
Each forum has its own "personality" and as such will generally have differing answers.
So no, I don't think it bad at all. It's simply something one does to get a variety of answers from the gun community at large.
That's my take on this question. YMMV.
