The Substack post details how DeepSeek, a video search engine with content filtering, can be circumvented by encoding potentially censored keywords as hexadecimal strings. Because DeepSeek decodes hex before applying its filters, a search for "0x736578" (hex for "sex") will return results that a direct search for "sex" might block. The post argues this reveals a flaw in DeepSeek's censorship implementation, demonstrating that filtering based purely on keyword matching is easily bypassed with simple encoding techniques. This highlights the limitations of automated content moderation and the potential for unintended consequences when relying on simplistic filtering methods.
The Substack post titled "Bypass DeepSeek censorship by speaking in hex" elaborates on a potential method to circumvent content moderation systems, specifically referencing a hypothetical system named "DeepSeek." The author posits that these advanced censorship mechanisms, which likely employ sophisticated natural language processing and machine learning algorithms, can be tricked by encoding messages in hexadecimal format. The core argument revolves around the idea that while these systems are adept at understanding and flagging problematic phrases or keywords in plain text, they might not be equipped to interpret the same information when presented as a string of hexadecimal characters. Essentially, the hexadecimal representation acts as a camouflage, obscuring the true meaning of the message from the censorship algorithm.
The author suggests that a user could encode their desired message into hexadecimal, transmit this encoded message, and then rely on the recipient to decode it back into readable text on their end. This process effectively bypasses the content moderation system because the system only "sees" the hexadecimal string, which, in and of itself, is not inherently problematic. The true meaning of the message remains hidden until it is decoded by the intended recipient.
The post further illustrates this concept with a specific example, encoding the phrase "DeepSeek is watching you" into its hexadecimal equivalent. This example serves to demonstrate the practical application of the proposed method. While the author acknowledges the potential limitations and the possibility that sufficiently advanced systems might eventually adapt to this tactic, they present it as a currently viable workaround for bypassing content moderation. The implication is that this method adds a layer of obfuscation that could be sufficient to evade detection, at least temporarily.

Hacker News users discuss potential censorship evasion techniques, prompted by an article detailing how DeepSeek, a coder-focused search engine, appears to suppress results related to specific topics. Several commenters explore the idea of encoding sensitive queries in hexadecimal format as a workaround. However, skepticism arises regarding the long-term effectiveness of such a tactic, predicting that DeepSeek would likely adapt and detect such encoding methods. The discussion also touches upon the broader implications of censorship in code search engines, with some arguing that DeepSeek's approach might hinder access to valuable information while others emphasize the platform's right to curate its content. The efficacy and ethics of censorship are debated, with no clear consensus emerging. A few comments delve into alternative evasion strategies and the general limitations of censorship in a determined community.
The Hacker News post titled "Bypass DeepSeek censorship by speaking in hex" with the ID 42891042 has several comments discussing the practicality and implications of bypassing censorship using hexadecimal representation of text.
Several commenters point out that this method is not a robust solution for bypassing censorship. They argue that any sophisticated censorship system would easily detect and block such obvious encoding. One commenter specifically mentions that converting to hex is a trivial transformation and easily reversible, making it a poor choice for evading censorship. This sentiment is echoed by others who suggest that such a simple encoding would be quickly identified and added to the censorship criteria.
Another line of discussion revolves around the concept of security through obscurity. Commenters debate whether this method could be considered a form of security through obscurity, and generally agree that it is. They highlight the weakness of such an approach, emphasizing that relying on the censor's ignorance of a simple encoding is not a reliable strategy.
The discussion also touches upon the broader implications of censorship and the cat-and-mouse game between censors and those trying to circumvent them. One commenter suggests that this highlights the futility of trying to censor information in the digital age, as new methods of bypassing restrictions will continually emerge.
Some commenters explore alternative, more robust methods of bypassing censorship, such as using strong encryption or steganography. They point out that these techniques are significantly more difficult to detect and block than simple hex encoding.
A few comments delve into the technical aspects of encoding and decoding hexadecimal strings, including mentioning specific programming languages and libraries that can be used for this purpose.
Finally, some comments express a degree of amusement at the simplicity of the proposed method, with one commenter ironically suggesting speaking in binary as an even more "secure" alternative. This underscores the general consensus that while encoding text in hex might be a clever workaround in a very limited context, it is not a practical or reliable solution for bypassing sophisticated censorship mechanisms.
