Wow. Just when I thought DQs couldn't get any more unreasonable (or even laughable). Though it is the rules and they have every right to do so, I hope QATs do judge with a level of reasonableness when it comes to DQs. It isn't very convincing to bring down the whole mapset if the only problem you can find is a petty spacing issue (or even a misunderstanding?) in the Easy difficulty. Though it may have started with a good intention to improve the map, I feel that this DQ was unjustified and rather thoughtless. I think that unnecessary and unjustified DQs should be kept to a minimum as they do more harm than good for the community.
Again, QATs do have every right to decide whether something should be examined and fixed in the Qualified state and there's nothing wrong with doing their jobs. But I do think they should reason and communicate with more transparency to the mappers/BNs about their decisions . Not just "Good luck!"
Just my two cents.
