Terms of Service

1. Overview and Scope

Welcome to perciocastelo.com.br. This website is an independent technical portal authored and curated by Percio Castelo (known in developer and security circles as sr00t3d), dedicated to real-world Linux infrastructure engineering, system administration (SysAdmin), DevSecOps, cybersecurity audits, open-source tooling, and professional consulting engagements.

These Terms of Service govern your access, navigation, use of published technical scripts and guides, interactions via comment forms, and any technical service requests submitted across this domain, its subdomains, and accompanying utilities.

2. Agreement to Terms

By accessing, browsing, interacting with, or utilizing any feature, code snippet, or documentation on this site, you acknowledge that you have read, understood, and agree to be bound by these Terms of Service and by our Privacy Policy.

If you do not agree with any provision of these terms, you must immediately cease accessing and using this portal.

3. Technical AS IS Disclaimer (Infrastructure & Security)

Performing operational modifications on production servers, operating systems, and network stacks carries inherent risks of service downtime, authentication failure, administrator lockout, and data loss.

• Administrator's Sole Responsibility: You, as the administrator or engineer executing commands, bear the sole and unshared responsibility to review, audit, create full backups, and validate any script or command in an isolated staging/lab environment prior to deploying it to a live production server.
• Provisioned "AS IS": All information, tools, and code are provided on an "AS IS" and "AS AVAILABLE" basis, without warranties of any kind, whether express or implied, including, but not limited to, implied warranties of fitness for a particular purpose, non-infringement, or cross-distribution compatibility.
• Limitation of Liability: Under no circumstances shall Percio Castelo be held liable for any direct, indirect, incidental, consequential, special, or punitive damages, including loss of revenue, business interruption, or data corruption arising from the use, application, or misapplication of any command, guide, or script found on this site.

4. Intellectual Property & Open-Source Licensing

Open collaboration and attribution are core tenets of this platform:

• Editorial & Written Content: All articles, guides, and textual tutorials published on the blog are licensed under the international Creative Commons Attribution-NonCommercial 4.0 International License (CC BY-NC 4.0). You are free to share and adapt the material for non-commercial purposes, provided you give appropriate credit to Percio Castelo and provide a direct link to the original article.
• Source Code & Open-Source Utilities: Unless explicitly noted otherwise within specific file headers or project repositories, all software utilities, automation scripts, and code snippets authored by Percio Castelo are released under the MIT License.
• Third-Party Trademarks: All third-party trademarks, product names, logos, and brands cited (e.g., Linux®, Ubuntu, Debian, Red Hat, CentOS, cPanel®, DirectAdmin, HestiaCP, WordPress®, Cloudflare®, Stripe®, Google®) belong entirely to their respective holders. Their mention on this site is purely nominative, educational, and descriptive of system compatibility, carrying no implication of endorsement or formal sponsorship.

5. Code of Conduct for Comments & Community Interactions

Comment sections and feedback channels are provided to foster high-level technical discourse, problem-solving, and professional knowledge sharing. By posting, you agree to:

• Maintain a respectful, constructive, and ethical standard of communication toward all peers and the site author;
• Refrain from posting defamatory, abusive, offensive, unlawful, or discriminatory statements;
• Avoid posting unsolicited commercial messages, link farming, spam, or promotional campaigns;
• Never attempt to inject malicious code (XSS payloads, malicious shell commands, or exploit links) intended to compromise browser or server integrity.

The author reserves the absolute right to moderate, redact, or permanently delete any comment or submission that breaches these rules without prior warning.

6. Professional Services & Consulting Engagements

Technical publications, benchmarks, and portfolio case studies featured on this website do not represent binding commercial proposals, nor do they create a client-contractor relationship.

Formal consulting arrangements (including Linux server hardening, high-availability architecture, DevSecOps pipelines, disaster recovery, or emergency incident triage) are established exclusively through formal technical scope discovery, bilateral contracts, and clearly defined Service Level Agreements (SLAs).

7. Affiliate Links & Commercial Transparency

In strict compliance with consumer protection legislation and international trade commission guidelines (FTC 16 CFR Part 255):

We openly disclose that select outbound links across the site (specifically routing via /go/{slug} and comparison pages) are affiliate links. Should you choose to purchase or subscribe to an infrastructure service or software tool via these referral links, we may earn an affiliate commission at absolutely zero additional cost to you.

All recommendations reflect authentic operational experience, real-world deployment benchmarks, and independent technical scrutiny. Technical integrity always takes precedence over commercial affiliations.

8. Voluntary Donations & Community Sponsorship

This portal provides an optional voluntary sponsorship channel via our Support & Donate page (powered by Stripe).

Contributions are entirely voluntary and non-refundable, intended solely to offset hosting overhead, staging server fees, hardware testing, and ongoing maintenance of open-source projects. Donations do not convey equity, ownership, or preferential technical support guarantees.

9. Amendments to Terms

These Terms of Service may be updated periodically to account for platform enhancements, architectural updates, or emerging legal requirements. Revised editions take effect immediately upon being posted on this URL with an updated timestamp.

10. Governing Law & Jurisdiction

These Terms of Service are governed by and construed in accordance with the laws of the Federative Republic of Brazil, notably the Brazilian Internet Civil Framework (Law No. 12,965/2014), the Civil Code (Law No. 10,406/2002), and the General Data Protection Law (LGPD - Law No. 13,709/2018).

Any dispute arising out of or related to these terms shall be subject to the exclusive jurisdiction of the competent judicial district of the author's domicile in Brazil.
