Suing Robinhood

I deleted my Robinhood account 3 years ago. At the time, I asked them to remove all my personal information, but they declined. A short while later, they had a security breach and leaked my email and other personal information to the dark web. Now I get persistent crypto scam emails. This is annoying. And still, three years later, after not having an actual Robinhood account, they’re still sending me promotional emails. They don’t have an unsubscribe button as required by law either! I hate this company so fucking much.
