It always helps to attend Linden meetings. The question of the Zorkmid system legality came up today at the governance team meeting today. TOS prevents me from quoting the chat (even though it was public) but the gist of it was:
Q: Are the $Z (instead of L$) casinos legal?
A: Yes, the system we've seen is legal.
Q: So its like the return of casinos, but legal?
A: That's exactly right, it's legal.
Sorry people don't like games of chance, but why it matters so badly to prevent others from doing it eludes me. Why does it matter to non-participants?
