Ok i received an answer from them.
I wrote yesterday to Yukon Gold:
Hello!
My name is XXXXXXXXX. I live at XXXXXXXXXXXXXXXXXXX. Yesterday i've received your envelope at my home adress, containing your commercial and a CD with your casino software.
Why i am writing this is that i never registered at your site (Yukon Gold) or never agreed to receive any commercial product, real mail or email from you. I'd like to know
how and where did you get my personal data, so i can pursue the violators of privacy policy.
And beside that i demand that you immediately remove my adress from your mailing list, because i assume you don't have the right or my approval to send any letters or emails to me. If i enter my personal data anywhere, those sites are trusted.
I really hope that was only a mistake or misunderstanding and i wish you'll resolve this issue quickly and reply my with proper data.
Thank you for your time!
Best Regards!
Their answer:
Hello XXXX,
As a representative of the Customer Loyalty Team I have happily looked into your inquiry.
Unfortunately and with deep regret, it is not possible for us to isolate where your details were obtained. However we can disclose that somewhere along the line you signed up or registered your details with a service and agreed (or choose not to disagree) to the use of your personal information. All we can suggest is perhaps trying to back track to any companies that you recently registered with and check their privacy statement policy.
I confirm that all your details have now been deleted from our mailing list.
I apologize for any inconvenience caused.
We are endlessly striving to better our service. If there is anything more we can do for you, or if we could improve your experience, please do not hesitate to let us know. We are always here for you - 24 hours a day, 7 days a week, 365 days a year.
Thank you and kind regards,
Lauren
Customer Loyalty Team
No go figure who is a violator. The fact that they don't want to disclose the culprit is telling us that someone broke the privacy policy.
