The user hasn't been banned, but hasn't posted either, so there could be a temporary ban.
Umm.. seeing that he just posted below your post I believe he was not banned, or not yet. Let's see how things will develop though... If he's lucky enough he'll end up just with having one post deleted, which is not hard to live with. However, even if it will be so, I think he learned his lesson.
I apologize for my unintentional mistake which was not made with the intention of gaining any advantage. It was simply due to my laziness and I would be grateful if you could forgive me.
Just curious though: why did you make the post? Since you had clearly absolutely no reason to vote (otherwise you would certainly spend some time to think about who to nominate) why did you make that post?
Excepting the above question, have you ever considered of implications of such behavior in case dozens of users would do it? Imagine someone would nominate multiple users which would not deserve to be nominated and after that a dozen copy-paste his vote. This could lead to (1) having an incorrect winner (or more) and / or (2) to have the one counting votes spending a lot of precious time in vain, just to analyze copy-pasted votes in order to not count them.
Seriously, why act like this? For what purpose?
Honestly speaking, the reason I made the post was to express gratitude towards Shahzad Afzal's significant contribution to our local community on the Bitcointalk forum, where he provides valuable information about Bitcoin and technology. I also wanted to acknowledge his efforts in attracting new members. This is why I followed his voting decision and included him in the Craft Master category."
