Oops! I didn't mean to imply that you were "bad"!
I understand your intentions, and it is quite possible that someone might only cruise a given forum.
That whole issue, and general social attitudes about "crossposting", is a long-time point of contention on UseNet and on many other internet forums. Generally speaking, it has been my experience in most forums (and particularly in this one) that you are better off picking the "fourm" where you feel you are most likely to get the desired help, and go with that until/unless that doesn't get you a response.
Many of the more prolific posters that provide the most help just don't want to mess with keeping track of multiple threads that are all discussing the same thing.
Crossposting also can double, or triple, the amount of reading/searching a user interested in the answer to your question has to go to see everything that has been said.
