Interesting stuff... First of all, sorry for your "loss" @OP.

The guy representing Satoshidice/Cryptodice recently contacted me to get featured on my site and when I told him I am not adding a "random" site before I know they are 100% legit and therefore asked for some sort of security, I never heard back of course.

I will msg him and ask him to check this thread even though I guess I will simply be ignored.

Nb. I really think it's about time to add some crypto casino blacklist on my site...
