They called and the person told me it was the Walt Disney Concert Hall calling. They said they "noticed" I was a "Hollywood Bowl Go-er" and did I know that ____ _____ was their new conductor. I told them I had been to the Bowl twice, so I guess buying tickets got me on a list. They sounded shocked I had only been to the Bowl twice, and before they could try to convince me to go more, I hung up. I used to ask people like this to take me off of their lists, but it never works.
Whatever you do, don't give your phone number to L.A. Phil when you order a subscription, they will pester you forever trying to get you to buy more tickets/subscriptions.
