I tend to agree with the brand boost theory. In the examples I'm seeing, they are posted on sites that would like have some elements of trust, even if they are off topic for the search. And many of the queries are in low trust categories.
I agree that they'll be killed eventually. It's just odd to see such irrelevant results in trophy term searches. I'm actively monitoring how long "due time" will be.
