As you can see, such opinions don't help users at all. They're posted solely for Xper hunting. These opinions can be submitted to any question out there. They should be hidden under "non-sense" (or any other reason) as they are lacking information and is implicit spamming.
I mean, if you don't know, why answer?
- Yes. It should be bannedVote A
- No. Such answers are importantVote B

I don't think anyone's answers to anything should be banned. What kind of OPINION website would ban people's opinions just because you don't think they're useful?
Those kinds of opinions should let you know that you didn't articulate your question well, or that, God forbid, someone isn't able to take a definitive stance on an issue. Believe it or not that's actually the most common and sometimes more intelligent response.

I believe that opinions where you qualify (i. e. "Maybe," "I don't know," "one or the other") are valid answers, but only when you explain why.
One could extremely easily go on the relationship section, not even read the question, and type in "idk" as an answer. In the rules like you mentioned, I believe it actually would count the "idk" statement as "nonsense" technically (it gives "lack of details"). However, it is rarely hidden.
If someone asks a question like "Do they like me?" answering "I don't know" tells them absolutely nothing. Why? Because they are asking the question in the first place! Why would someone ask a question about relationships or serious topics if they knew the answer already?
That being said, if there is a question that describes a person giving mixed signals and the person really could be going both ways, I can understand an "idk" answer... But only if they explain why! Explaining basically helps say, "I read your question, but I don't think there is enough evidence to support either side. I can't choose a side because of that."
Nevertheless, while I may not always hide them (though sometimes will depending on question/answer), they still annoy me :/
On the ones you mentioned...
-- "I don't know" -- already explained position
-- "Do what you want" -- generally valid depending on question, especially if given more substance to answer
-- "I'm confused" -- valid. Questions can often be worded weirdly
_ "haha lol" -- invalid on serious/legit questions, but valid on questions meant to be humorous
-- "probably" -- valid. I see probably as meaning mostly yes, which at least takes a side.1
