Claude's game rule

Tom's Hardware's headline says sweeping new Claude restrictions block game cloning and reverse-engineering.

Correction · 2 Nov 2026

A different-vendor re-check found the story leaned in Anthropic's favour. It used "two sentences" to suggest the rule had little effect, left out Anthropic's own post on cyber blocking, and read a sentence about timing as doubt about the refusals. The old call was ambiguous, because that post already names malware reverse-engineering as work for a verified tier. BS Killer is built with Claude, so the story should have said so from the start.
Previously: The ruling was True, but. The story called the game rule real and small: two sentences, not sweeping restrictions. It filed the reverse-engineering refusals under user claims and quoted Tom's Hardware's line that the timing "may be a coincidence" as if it doubted the refusals, cutting it before "and yet there are complaints". It told reverse-engineers to treat refusals as unexplained, and it left out Anthropic's 6 October Cyber Verification Program post, which Tom's Hardware links. The call read: "By 31 December 2026, Anthropic will not publish a rule that names reverse-engineering or troubleshooting tasks as blocked in Claude Code."
Corrected: The ruling is still True, but. The game rule is confirmed, and the story now cites Anthropic's 6 October post, which says its generally available models "have conservative cyber safeguards that block most cyber work" and lists reverse-engineering malware as work for its Defense Access tier. Refusals of game reverse-engineering and everyday troubleshooting are still user reports. The coincidence line is quoted in full, as a point about timing. The call is narrowed to an explicit Claude Code rule, and the story now discloses that BS Killer is built with Claude, from Anthropic.

The claim we checked

Anthropic's Claude AI blocks video game cloning and reverse-engineering, with sweeping new restrictions that also hit legitimate developers and basic troubleshooting tasks.

These are quoted receipts, not a count of independent investigations. Several reports may rely on the same original source.
