mod_tombstones: Remember deleted accounts #1307
Presence subscriptions are normally revoked on account deletion, which
informs the contact. Sometimes this notification gets lost e.g. due to
s2s problems. The accounts JID may also be present e.g. in MUC
affiliations, chat group member lists, pubsub subscriptions or other
systems. These may grant privileges which would fall to someone who
creates the same account again, which this module is meant to prevent.
