If I understand the proposed system

Every entity has a public key.
Leechers issue IOUs to seeders. This creates a network of IOUs. The
pledgeroute software looks for ways to cancel out IOUs, thus honoring
them - for example Ann seeds Bob, Bob seeds Carol, and Carol seeds Ann.
If your IOUs get cancelled out, your key gains reputation, causing your
IOUs to be valued.
It is not clear to me how the sybil attack is avoided: Is it that you
only gain reputation with those benefiting from the cancellation?

No matter how many Sybils a person creates, the total debt owed to them
by non-Sybils is limited by the total amount of service they provide. So
there's no advantage in creating Sybils. It's not impossible - it's just
pointless.
But sybils will report that a sybil pays his debts, thereby encouraging
non sybils to erroneously grant him credit.
