GBz prohibits unsolicited bulk or commercial messages, phishing and other abusive messaging activity.
Prohibited activity
You must not use a GBz service to send or help deliver spam. Messages must not use forged headers, deceptive routing, misleading sender information, unauthorised third-party domains, harvested addresses or false content.
You must not use GBz to collect addresses without permission, operate open relays, distribute malware, conduct phishing, or repeatedly contact people who have not agreed to receive the message.
Enforcement
We may investigate suspected abuse and block messages, domains, accounts or network addresses. A service connected to spam or related abuse may be restricted, suspended or terminated without advance notice where prompt action is needed to protect the platform or others.
Report abuse
Report suspected spam or abuse through the GBz contact page. Include message headers and relevant evidence where available, but do not send passwords or private keys.
