I've seen these kinds of things in the past. I can say first hand that I for one do not read the questions... type gibberish in text fields and select random choices in multiple choice answers. I am sure others will do the same.

I don't see how this can work. The only time I see it some-what-working is while gathering a massive (really massive) amount of submissions for a decision involving only two options. Maybe then... but even then it wouldn't be possible to determine the actual percentage of users suggesting one or the other option.
