Overview

This Acceptable Use Policy (AUP) applies to all services provided by ClusterHosting. By using our services, you agree to comply with this policy. Violations may result in immediate suspension or termination without refund.

• Hosting, distributing, or linking to illegal content of any kind
• Child sexual abuse material (CSAM) — zero tolerance, reported to authorities immediately

SMTP and email

Only outbound SMTP port 25 is blocked by default. Ports 465 and 587 are not blocked by this policy. Port 25 unlock availability depends on account and provider eligibility and may not be available. Sending unsolicited or abusive email remains prohibited.

Network usage

Each plan includes a fixed traffic allocation. Exceeding your traffic limit will result in network throttling or suspension until the next billing period. DDoS traffic directed at or through your server is prohibited regardless of source.

Reporting abuse

To report abuse involving our IP ranges, contact [email protected]. Include logs and relevant evidence. We take abuse reports seriously and respond promptly.

Enforcement

We reserve the right to suspend or terminate any service found to be in violation of this policy, with or without prior notice, at our sole discretion. No refund will be issued for terminated accounts.
