Disappointing experience in first 3 minutes of registering

Signed up on the website using the free $ coupon/link. After filling in the form and paying with my personal paypal account I got automatic rejection of account.

Stumbled upon similar problems online so I wrote a message to support and within minutes got automatic reply with something in the line of our system decided not to give you an account.

I am not sure why this happened but I believe the coupons are usually made to attract new customers, however in case of digital ocean they are loosing customers straight after onboarding which in my opinion is a waste of time and resources at lead generation.
