Not very polite, neither enlightenment... I can image that Alice and Bob would never talk each other again, 'cause they would think that the other wan't to have other's 'contact'.... :)
Well, IMHO is worse if the presence server replies 200 for the SUBSCRIBE and inmediately rejects the subscription with a NOTIFY containing "Subscription-status: terminated;reason=rejected". In this way it really seems that bob has blocked alice. In the other hand, if the proxy responsible for bob rejects the SUBSCRIBE from alice with 403 it's clear that it's a realm/inter-provider issue.
