X平台根据巴西选举法规实施了针对2026年大选的内容过滤机制[1]。该过滤器通过识别已向巴西最高选举法院登记的候选人用户ID，自动从用户推荐信息流中排除这些候选人发布的内容[1]。根据公开的代码，超过600位巴西候选人的用户ID和用户名被纳入过滤列表[1]。
这一举措遵循巴西选举法§ 1º条款，该条款要求使用推荐系统的应用程序提供商必须排除向选举法院报告的渠道和资料中的内容[1]。过滤机制的候选人数据来源于巴西最高选举法院的开放数据库[1]。值得注意的是，付费推广内容不受此过滤限制，仍可在用户信息流中显示[1]。实现这一过滤功能的代码规模为1573行（其中1532行为有效代码），文件大小为39.9 KB[1]。
X has deployed a content filtering system designed to comply with Brazilian electoral regulations ahead of the 2026 presidential election.[1] The mechanism operates by identifying user accounts belonging to candidates officially registered with Brazil's Superior Electoral Court and automatically removing their posts from users' recommendation feeds, with the exception of paid promotional content.[1]
The filtering system draws candidate data from Brazil's Superior Electoral Court's open database and encompasses over 600 verified candidate user IDs integrated into the filter list.[1] According to § 1º of the applicable regulation, applications utilizing recommendation algorithms are required to exclude content from channels and materials reported to the electoral authority.[1] The implementation consists of 1,573 lines of code—1,532 of which are functional—totaling 39.9 kilobytes in file size.[1] Paid promotional posts bypass these restrictions and continue to appear in users' feeds.[1]
