Got banned from Chase last year but was somehow just approved for a credit card?

Also posted in r/Chase

I got banned from Chase last May from what I believe purchasing crypto from Coinbase; they sent me a letter saying they were closing everything of mine (checking and my 5 credit cards) within 30 days.

I just saw that the Marriott Boundless had a big sign up bonus going on and since I will be traveling a lot in the upcoming months, I decided to try to apply for it before applying for a Marriott AMEX card instead. Well, somehow my application got approved?

Has anyone experienced this before? Will I just get my card cancelled after a few days when they realize that I'm banned?

Thanks!
