Why Was My Post Downvoted? - An Open Message To @dantheman

So I was a left a bit disappointed the other day when I logged onto Steemit and I checked my past posts, one of which I knew was due to give me a $500 payout. It's meant to be 4 hours from now, but the payout is gone thanks to a down vote from one of my favourite contributors AND curators @dantheman. Frankly I'm quite confused, I was very lucky that my post started trending after the initial 24 hour pay out period and I knew that I'd be getting a nice payout one month later.

UPDATE: Now all the up votes on the post have disappeared too! It had 214 yesterday..

This is the post, now there's a few reasons why this worries/annoys me.

1. What did I do wrong? Firstly, if I did something wrong I need to know. I love Steemit and I want to continue being a constructive member, it's hugely discouraging for me if a post has been down voted and I can't even find a discernible reason for it. It would be really constructive if down voters gave a reason in the comments, especially when it's a Whale so that the poster can understand why this has happened and avoid doing it again. It's pretty obvious that my post was personal, original and definitely not plagiarised.

2. Censorship. One of the things that is a promising aspect of Steemit but also a huge potential problem is censorship. As the popular @barrycooper pointed out there is still a massive issue when Whales pick posts they don't like and down vote them. This greatly hinders the idea of no censorship on Steemit. Now I don't know if @dantheman disliked my posts because honestly he's up voted my posts more than any other whale, but when I don't have an obvious reason it allows my mind to run wild with ideas. My post had 212 up votes and 1 single down vote from @dantheman, I think that if I had done something universally despised I would have gotten a lot more down votes than that.

On another level this came at a bad time for me. It's my 21st birthday on Monday and I was hoping to get this pay out in time for my birthday weekend, obviously this is a personal reason that is not related to anyone else but it affects my thinking when using Steemit.

All I want is to know why my post was down voted, I honestly don't care about the payout as I've made plenty on Steemit and I know it's not all about the $$$. But if I want to continue openly contributing to Steemit I need to know what I did wrong if I even did anything undesirable.

Hope to find out what happened.

THANKS GUYS! :)
