The SubmitBadSignatureEvidence is not actually registered in the handler and hence no one can actually submit this message, rendering the message useless. This harms the security model of Gravity since validators have no disincentive to attempt to collude and take over the bridge.
The SubmitBadSignatureEvidence handler is omitted from module/x/gravity/handler.go
Visual inspection
Handle the MsgSubmitBadSignatureEvidence in module/x/gravity/handler.go
