Most people’s social media accounts are digital attics filled with decade-old posts that no longer represent them. There’s real value in cleaning this up—not just for privacy, but because algorithms use your history to rate you and determine your reach. While platforms may keep backups, what matters most is your live profile and recent activity. By deleting old content and strategically posting smarter material, you can effectively reset your algorithmic reputation and eliminate attack surfaces for those who might weaponize your past against you.

Activist groups can transition away from Big Tech platforms by following a structured roadmap that emphasizes digital freedom and community resilience. This approach involves understanding the risks of platform dependency, addressing hidden barriers, engaging members, and testing alternatives before full migration. By aligning with the 12 Principles of Digital Freedom, groups can build independent, secure, and impactful communication systems while maintaining reach and trust.

This text, part of a Digital Freedom Awareness Week project, explains how identification methods can be weakened and how systems defend against such attacks. It outlines 10 methods, their counter-measures, and combinations most likely to bypass security, especially under scale and cost constraints. The content is intended for educational and transparent use only, emphasizing ethical and lawful application.

Big Tech platforms use secret, evolving keyword lists to moderate content, which are never fully disclosed. While official policies describe content categories, actual trigger words are kept proprietary. Leaks, academic studies, and transparency reports provide partial insights into these systems. Keywords related to hate speech, misinformation, violence, and spam are commonly flagged. Context, user history, and platform-specific algorithms determine moderation. Open-source datasets offer approximate maps for awareness, but internal lists remain undisclosed.

Large platforms like Google use multiple image scanning levels, from lightweight fingerprints to deep analysis for safety, abuse prevention, and deduplication. While they don’t disclose full details, common triggers include sensitive content, copyright, and misinformation. Deep scans are applied selectively due to privacy, policy, and scalability constraints. A practical approach involves tiered checks based on risk, balancing security and efficiency.

Identifying images online involves combining multiple techniques, including file size and signature analysis, to detect visually similar or identical images across platforms. Google and similar systems use layered signals and heuristics to match images, even when resized or framed as memes. While no single method is perfect, a combination of approaches improves accuracy. Challenges remain with edge cases, such as heavily edited or low-quality images.
