It ensures controversial questions will never get asked.
To the contrary I'd say that the questions players are most keen to get answered will be more likely to receive an answer. The top voted questions are often seen as "controversial" in the players eye.
If you say controversial are not being asked because they are down voted, I would rather assume that the person isn't interested in that question being asked and that they would down vote it because they don't think it's worth the time.
On as side note we specifically asks players to only up vote in this thread, which is exactly what is happening afaik.
Those at the top will always get seen and this voted, but later asked questions won’t. That’s why I delayed my comment with a list of questions.
The subreddit mods have been very helpful to avoid this and they put the thread into randomised mode. which they've now disabled so there is transparency and we can prioritise the questions along side the other ones we've received.
your goal should be to answer as many questions as you can and organize them so teams/people can answer them.
We aim to provide as many in-depth and meaningful answers to questions that are gaining the most traction within the community.
You have posted a list of questions and if the community would only up vote that post because of one very important question, we would end up in a situation where we would be answering your other questions, deemed less important by the community, over others which the community is more keen to see us answer.
