My account on betfury and two other casinos have been inactive for over a year now, ive never recieved any email from any of this casino calling my attention to any prepared bonus to get me to be active with my account again lol.
I haven't visited Betfury for a long time, but a few days ago I got an email to claim a bonus code given in the Champions League and Tennis events. I also got the same email from other casinos. Giving bonuses, even though they are small, whether with conditions or not, is indeed given to users who have previous activity and then stop.
