If it's not GDPR compliant can it still be used?

A credit is applied when an e-mail is found. In the youtube video https://youtu.be/xC4KHUyzt-4.
It doesn't show how much e-mails were found it just took the total number of businesses and on top of that if you want to find a manger, for example, in the business or any position you are charged another credit.

Why should we be charged twice, why does it charge once for an e-mail of a person in a business for the position ie. JimTacos manger Jim. You should only be charged once for Jim's e-mail. Not charged once for the business and once for the position of manager for a total of two credits assuming that there is an e-mail. The video shows that the user is charged twice regardless of e-mails found. Is this video wrong?
