There’s a post about the American Express platinum card offer of 150,000 points and gold card offer of 90,000 points. You don’t need to send a PM to get it as it’s not secret.

[Expired] [YMMV] American Express Gold 90,000 Points + 20% Back On Restaurants - Doctor Of Credit
Amex Plat - 150K Bonus Point; Gold - 90K Referrals
The platinum offer would give you at least 156,000 points, which is worth $1,716 cash if you also have the Schwab platinum card to get the cash out ability, so $1,716 minus $695 equals over $1,000 cash for spending $6,000.
But you really should read up at Doctor of Credit and Reddit to know which cards to sign up for first. Many people go to Chase first due to the Chase’s denial if you signed up for 5 credit cards in the last 24 months.
