-When you create an quiz and play it, you can write an answer and surrender. Your stadistics doesn't sum up with the average ones; but what does sum is your own attempt with the general ones. So if you start, surrender and re-start you can get infinite takes on your own quiz!
This is obviously a bug, not a feature.
That means that I could play my quizzes 10k times each and fake all my stats
But in regards to (2), the stats that show up for any quiz have to do with a user's first attempt at the quiz.
-1: Create a quiz
-2: Play it, write an answer and surrender
Your stats won't modify the general stats
-3:Congrats! You now have added a visit on your own quiz!
If this won't get parched, I would play my own quizzes 16 times, just writting an answer, and I would get 16 visits to it...
But the intent is for that to not affect the answer stats. The answer stats are supposed to reflect a user's first attempt. Otherwise people will be taking quizzes over and over to get the 5/5 points, but then the answer stats will be too high (making it very difficult to earn points on featured quizzes).
May your words become "The book of proverbs".
If you try to boost your own take count and we catch you we will just ban you and delete your quizzes. It's very easy to detect.
And, yes, this has happened in the past.
