When situations such as these arise, the onus has to be on the business provider to make a statement. Quite clearly a data breach could have occurred and if that is the case the company should be sending out emails to their customers/clients to advise them of the breach (and probably advise them to change their password).
If that did not happen, maybe the company is sending the email out deliberately in that format in order remind the customer he has an account there but doing it without email marketing. In recent times the reputation of Cloudbet did go down because of multiple scam allegations, at is stands I would not remove that possibility.
3 months since no one posting in this thread. I'm posting here today because something strange happen to me, that I received an email from cloudbet support this
An account is already registered to this address: (email address)
I don't know why I received an email like this since I'm not doing anything with cloudbet account and never visited it again. As i remember the last time I played in this website was 3 years ago and haven't received any email promotions since I unsubscribe to the email newsletter promotions. Does anyone of you who played in this casino experience the same thing?
