This is the fear of many people with mental illness: gangstalking.
Published (1961) before Kurt Cobain (and myself) was born.
On the other hand, my attempts to search for the word "paranoid" in the book on Amazon turn up nothing. And there is a semi-authoritative page that makes the same claim that you do, saying that the closest he found is a quote about a "persecution complex": https://quoteinvestigator.com/2016/07/09/paranoid/
Do you have more info?
If multiple sources are saying it is, they must be getting the idea from each other.
We can't just disregard all of the claims, we also can't just credulously believe every claim, but they also are numerous enough -- and difficult enough to investigate -- that we also can't feasibly do a thorough investigation of each.
I can say that in my case there's a decent chance that the goal was to drive me to paranoia and/or some form of public display that would get me labeled as a kook.
Essentially, drive someone to the point they go full 'space lizard rant'
Note that there are many more such sites if you choose to go down that particular rabbit hole.
