# kaal:claim:3125822-016

**Claim.** A 51 percent collusion that votes against common sense is visible in an open system, which erodes trust, reduces use and fees, and lowers the value of the attackers' own reputational salary, so the tactic can destroy an expertise tag but cannot enrich the attackers.

**Type.** mechanism  **Support.** argued

**Holds when.**

- requires an open and observable system
- assumes attacker value is held in the attacked tag

**Source quote.**

> This would erode trust in the platform, and therefore use and fees would diminish, making the 51% holding of reputational salary less valuable. Therefore this tactic generally has the potential to destroy the expertise tag, but not enrich the attackers.
