User shares tips to reduce false positives in Claude abuse checks

On November 3, 2026, a V2EX user posted a summary of what they say they learned by studying, together with Claude, the abuse-detection mechanism the company had most recently published. According to the post, after each reply Claude's back end evaluates the purpose of the entire conversation to decide what the user is actually trying to do, and users cannot see the evaluation records. The evaluation runs even when Claude refuses the request, the user added. Changing language, using homophones, splitting a question into pieces, or adding a phrase such as 'for research only' does not change the purpose of the request, they said. Being flagged is not the same as an immediate ban: the process officially disclosed aggregates records at the organization level, and only repeated high-priority flags are handed over for manual review, according to the post. The user says this has not affected their max account or their backup account restored after a prior ban, but they suspect it could affect shared accounts, since a user cannot know what others sharing the same account have done. The user says they hold two accounts, one on max and one kept as a backup after an earlier unban. Drawing on their own experience of being banned and then restored through an appeal, they advise that upon receiving a violation warning you should first stop the current task, check whether the request is ambiguous, and avoid rephrasing and retrying repeatedly; if you believe the flag was a mistake, use the official appeal channel. The post also notes that the company has explicitly prohibited sharing or reselling individual accounts. The user speculates, and labels it as speculation, that future crackdowns on relay or proxy services might involve small models analyzing an entire account's conversation history to spot anomalous use. A more detailed account appears in the user's video on Bilibili. As of this writing, this is the only user-reported account of the mechanism, and there has been no official response or independent confirmation.
