Are those credit card deals I see on Facebook legit?

I’m getting offered deals via Frequent Flyer on FB for the Amex Velocity Platinum card for 100,000 points if you apply before August 15th, yet both the Velocity and Amex websites state 50,000.

looks legit but if its not on the other websites one would assume its dodgy. anyone else come across this?

They are most likely via the Amex Referral program - this is designed for friends and family referral from existing cardholders. You can see the full terms of the offer by clicking through.
