Our analysis shows sufficient evidence of a unique Sybil attack targeted on this grant, which began promptly at the start of the round and stopped abruptly several days into the round.
Because this is a new attack vector and we cannot directly link the owners of the grant to this activity, we have decided not to deactivate the grant. We will, however, continue to take the usual action of disqualifying all Sybil donations from the quadratic funding allocation.
Furthermore, we believe that the brief period for which the grant was deactivated served as a counterbalance for the early momentum the grant received as result of the Sybil attack.
We believe this incident provides an important lesson for our community. If this type of attack becomes more prevalent in the future, then we reserve the right to deactivate such grants. We urge any grant that believes it is the target of a Sybil attack to alert us immediately, rather than wait for us to detect the activity.
