David Shepard of Visa (via a 3rd party, therefore not authorative):
....There are no restrictions in terms of participating in Verified by Visa except when the
merchant has "excessive" chargebacks or fraud and therefore, to protect Visa Issuers, falls
into one of the following Visa programs:
Global Chargeback Monitoring Program (GCMP): Merchants that are in this program due to
excessive chargeback volumes are not eligible for the "attempts" liability shift while they are in
the GCMP and for a period of 3 months thereafter; however, they may still participate in the
program and will receive the liability shift for fully authenticated transactions.
Risk Identification Service (RIS): If a merchant is identified as having excessive fraud, based
on crossing RIS system parameters of "reported fraud" (fraud reported to Visa by Issuers), a
chargeback window may be opened against the merchant that allows issuers to chargeback
transactions regardless of the liability shift. Exactly which transactions are subject to the
chargeback window is determined based on the type of RIS risk parameter/threshold that the
merchant's reported fraud volumes/amounts violated.

So let me make this simple. If their risk department thinks you're a risk, you don't get protection. If you're already in hot water and looking to Visa for some help, sorry.
