Excerpt from Forum Rules:
4. Members are allowed one and only one account. Members are responsible for any and all actions made under the account. After site registration, members are expected to post and engage in a constructive manner as a means of becoming a member in good standing.
5. Routine searches are conducted for multiple accounts or an IP address with multiple registrations.
6. A permanent ban means just that; it is permanent and the former member is not to open another account. Detection of an effort to bypass the rules will result in immediate, permanent ban of the member and the IP address.
