I do definitely see the 3 in a row recently which is abnormal.
Individual votes cannot be traced back to a user, even by moderators. The dev team probably could, but for a small case like this they wouldn't.
I've run what analysis I do have and can say that no single person has engaged in a major downvote campaign against you. One person did have a large number of downvotes against you, but has almost 5x as many upvotes for you, so it's far more likely they just have a lighter downvote trigger than most. (You also represent a very small percentage of that user's downvotes.)
There was another user with a moderate number of downvotes toward you, but this user's statistics show they vote down WAY more than they vote up.
I'm not saying you're not a victim, but you're not a severe enough victim that we can do much about it. I wish there was more I could do, but the thresholds are set to make sure only severe cases get attention.
