Each peer maintains its own safe credit margins for other peers based on the history of services exchanged with those peers. There's no way for a third peer to cause the first peer to exceed its safe credit margin for the second peer, even if the second and third peers are Sybils. The second and third peers can assign each other arbitrarily large credit margins, but when the first peer looks for a cycle, the amount of credit added to the links of the cycle will be limited by the lowest safe credit margin on any link (last paragraph of section V).
