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 & Interactive Tools: Unless explicitly noted otherwise within a specific file header or repository, original scripts, utilities, and software created by Percio Castelo are released under the terms of the MIT License.
• Third-Party Trademarks: All product names, logos, brands, and registered trademarks mentioned (such as Linux®, Ubuntu, Debian, Red Hat, CentOS, cPanel®, DirectAdmin, HestiaCP, WordPress®, Cloudflare®, Stripe®, Google®, and others) are the property of their respective owners. Their mention here is purely for identification, descriptive, and technical interoperability purposes, and does not imply endorsement, affiliation, or sponsorship.

5. Community Guidelines & Comment Moderation

The comment section of the blog is intended to foster constructive, technical discussions and peer-to-peer knowledge sharing. When submitting comments or feedback, you agree to:

• Maintain a respectful, professional, and constructive tone toward other participants and the author;
• Refrain from posting defamatory, abusive, harassing, unlawful, or discriminatory statements;
• Never post unsolicited commercial messages (spam), automated advertisements, or promotional links;
• Never attempt to inject malicious code (XSS, SQL injection), destructive terminal payloads, or links to malicious downloads.

I reserve the right to review, edit, moderate, or remove any comment that violates these guidelines at my sole discretion, without prior notice.

6. Professional Consulting Services

Content published on this website is for informational purposes and does not constitute formal legal, compliance, or dedicated technical consulting advice.

Engagements for professional services—including Linux infrastructure sustainment, DevSecOps pipeline engineering, cloud migrations, or incident response—are established through tailored technical scoping, written service proposals, and bilaterally executed contracts specifying exact scope, service level agreements (SLAs), deliverables, and fees.

7. Affiliate Links & Commercial Transparency

In accordance with the Brazilian Consumer Defense Code (Law No. 8,078/1990) and international consumer disclosure standards (including U.S. Federal Trade Commission guidelines):

Please note that certain outbound links on this site (specifically routed through /go/{slug} or noted in technical comparison reviews) are affiliate links. If you decide to purchase a service, security license, or hosting plan through these links, I may earn an affiliate commission from the merchant at no additional cost to you.

Every tool, hardware, and service recommended reflects my genuine technical experience in production environments. Editorial independence and engineering accuracy always take precedence over commercial affiliations.

8. Voluntary Donations & Sponsorships

Visitors may choose to support ongoing research, server lab costs, and open-source software maintenance via our Support & Donate page (via Stripe credit card checkout or Brazilian Pix).

Donations are purely voluntary, unconditional financial gifts. Making a donation does not establish a commercial purchase contract, confer equity rights, or entitle the donor to customized private support or physical merchandise.

9. Changes to These Terms

I may revise, update, or expand these Terms of Service from time to time to accommodate new website features or changing legal requirements. Updated versions become effective immediately upon publication on this page, and the "Last Updated" date will reflect the revision timestamp.

10. Governing Law & Jurisdiction

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

Any dispute, controversy, or claim arising out of or relating to the use of this website shall be submitted to the exclusive jurisdiction of the competent courts of the author's domicile in Brazil.
