Is lincolncasino.eu Safe?

When clicking the unsubscribe link I got taken to their webpage where there was no unsubscribe box. There was however a chat button so I used it to inquire how to unsubscribe and was asked personal info. Upon telling them that all they need is my email they proceeded to tell me they had to look up my account to unsubscribe me so I told them I didn't have or want an account from them and they told me I would have to have an account to unsubscribe. I then told them to blow it and left the site. Now doesn't that sound a little like phishing to you? Could you imagine what could happen if your kidd got on this website?
