Refrain from it.

Since you will be doing mass posting, forum moderators will very quickly catch you doing that, and probably will ban you.

This might do more harm. Its better going to events nearby you live and doing a talk with smart plugin of your product at the end.

Yes, but this post could not be treated as spam, but as a some kind of advice or something like that, or I can make much smarter submition like asking first, and from another account posting an answer.

That's still a spam. Moderators always treat new account created with pinch of salt and can be very aggressive as well. A new account asking a question, and new account answering it. This will surely be treated as spam.
