Where is the sites Terms of Gambling?

You just let people sign in with name, but fact is they didn't sign up for the so called "rules" you ask from them.
New users can't read them, each day there is new rule "can't multi roll on several accounts", "you cant roll with bank", " you cant refer your alt to yourself".

Then why allow several accounts on same ip?

Each one of those mutes, is was will be without a reason.
Do you really think people will come with common sense, that just stupid.
If you tell them there are rules in the bitcointalk forum, who will search 475 pages of spam.
