Why does YA hide some answers even though they have no downthumbs?

I sometimes see a note "1 answer hidden" among the answers when I respond.

I at first thought they were heavily disapproved questions, but that turns out not to be correct. I have looked at some of them, and they do not have any thumb-downs.

Any ideas, astute ones?

I found that some answers were hidden that seem not to have any reason for that, and I got email for answers that simply are nowhere to be found. Bizarre.

when you answer it yourself, it gets hidden sometimes

Short answered questions with one or two or just a few words usually get hidden.

It might be because of the answerer's prior record. I hardly ever go back and look at mine, so I don't know if any of them have been hidden.

They seem to be short answers, not very thoughtful. I've had a few of my sincere answers hidden, myself.

It's because they are the shortest, like this one lol
