Thankfully, one of those <strike>morons</strike> children has done it long enough so that I could take a video to better explain the problem. And as [you all can see](http://youtu.be/Cvekd2LzOuA), initially [with multiple stars](http://youtu.be/Cvekd2LzOuA?t=1m50s) to later [become redundant](http://youtu.be/Cvekd2LzOuA?t=3m32s),  this is quite annoying.

I'd suggest to block the user from starring (put a star on) any post for `x` hours after `n` (personal preference goes to the number 3) star/unstar actions within `t` hours.
