Flag Friend and PrivateMSG

Hi. Not sure if this fits entirely with the purpose of this module, but I think it would be great if it could integrate with Flag Friend and PrivateMSG modules so that when a user is banned, people who they interacted with (via said modules) will not be affected or confused.

For example. If a user sent some friend requests and a couple of private messages, then got blocked... The members they sent these to will be confused as to why their alerts say they have requests or messages, and when they click to go to the list, they don't see any. Not only would it cause confusion, but it would be impossible to ever get rid of those requests unless directly removed via phpMyAdmin or the user is un-blocked.

Like I said, not sure if this is the purpose of this module, but it would be great to fully clean up after a banned member :)
