I really don't care, to be honest. As long as the problem has been fixed through major changes to lifestyle and/or medication, plus enough time has passed to ensure that the person is stable, the fact that they once called a hotline is irrelevant.
I might not be as vehemently against the collection of this data if there were a strict retention limit written into law, perhaps 3-5 years, alongside a solid plan to properly enforce that limit and to keep records confidential.
As written, your comment implies that people can never change and situations can never improve. People regularly change their lives drastically, especially young adults whose brains are not even fully done developing.

I doubt that the fact that someone called into a hotline twenty years ago would allow anyone to make an accurate assessment as to their fitness to fly today. It would likely be used as a tool of oppression, and it would make people think twice before choosing to risk their future career prospects by calling into the hotline in the first place.
Permanently barring hotline callers from becoming pilots makes about the same amount of sense as permanently barring people who have ever had a broken arm from becoming pilots.
