As said by Darko: do not take this as deterrent.
There are some rules here (some written, some not).
Concerning this issue it says:
"Do not cross post a message in the forums (posting the same thread in multiple forums for more help/attention). Pick a forum, post the message, and let it be."
You'll find it under "Terms of Service (button at most upper bar).
I admit that button is hard to find and the respective text even harder to read. And even I after so many posts I do not know how some things work, or that certain features exist.
