Personally, I wouldn't recommend advertising the same quizzes on multiple message board posts since the same people who saw the last post are going to see this one, hence you will gain little to no plays from this second advertisement.
Also, you shouldn't stress too much over plays, they'll come naturally if you put effort towards making original quizzes.
I hope I didn't come off rude, that was not my intent. Good luck ;)
