As pointed out by @NVZ's answer, the large number of upvotes can be explained by the HOT.Network.Questions "HNQ effect" where Q & A  can be upvoted by members from all over the network, but they can't cast downvotes because they would usually not have sufficient reputation here. The 12 DV to 74 UV is also significant for this answer. A good answer might receive 74 UV but it will not receive 12 DV. It might be a fair assessment that at least 60 UV came from HNQ and obviously all 12 DV came from IPS. So many downvotes make it an advice to be treated with caution. That's why it might be sensible to default-display the vote score against every answer as a split score (split up into number of UV and DV), let readers make up their own minds!
