1. A computer-implemented method, comprising: providing item description information available for display via a network-based site concurrent with a corresponding item being available for sale via the network-based site; subsequent to the item description information being provided for display via the network-based site and subsequent to a submitter being provided, via the network-based site, with the item description information for the corresponding item offered for sale, receiving a correction submission specified by the submitter, the correction submission specifying a proposed modification to one or more item attributes in the item description information displayed via the network-based site; generating, via one or more processors, a risk score for performing the proposed modification to the item description information, wherein the risk score is based at least in part on a degree of change to the item description information represented by the proposed modification; and based, at least in part, on an evaluation of the risk score and one or more risk criteria, generating an indication that specifies whether the proposed modification to the item description information is permitted to be performed.

The computer-implemented method of claim 1 , wherein the method further comprises: receiving from the submitter of the correction submission, a network location of information serving as evidence for confirming the validity of the correction submission; retrieving information from the network location; and determining, via one or more processors, whether the information retrieved from the network location includes information that confirms the validity of the correction submission.
