@slaman29 @Trofo @icopress, we have received this message (email) for our inactivity in FortuneJack. The message was sent from the second email address which has been mentioned by Bitinity in the above reply. However, this is not a new thing in FortuneJack. They have rules about inactive account in their
terms & conditions.
2.7. If You do not log in to Your Account for a consecutive period of 12 (twelve) months or if no deposit has been made for a consecutive period of 6 (six) months after registering and opening the Account on the Website, Your Account will be considered a "dormant account" and We may block and terminate such dormant account any time after the lapse of above-mentioned time period.

But even if this is so, I do not want to lose my account at all, even if I have been inactive for some time (what if I had not seen this notification?).
We had created our account by accepting their T&C. So we have no option to blame FJ team if we missed to check our mailbox. Because it was our duty to read the rules of their terms & conditions. Few other casino have the similar rules like this. At least FJ has notified us about this issue. We can avoid this situation by contacting their support.
