Yup the workaround to limit dice drop is a nice trick. Yesterday I tried to re-register my username and shortly after that your site was in maintenance mode. Hopefully not because of me.
I also experienced that, during my registration. So I'm guessing it had nothing to do with you. Did some browsing around and I'm drawn in already, I am new to actual personal gambling, so do not have much to compare it with, but I can say I'm impressed with the layout and features.
