@dero @johnbillion This callback was added to resolve #1175. Please take a look.

Thanks @kidunot89 -- this callback will add an appropriate log entry, but AFAICT won't prevent the related "User removed" etc. entries from being logged, which can really clutter the log when a blog with dozens of users is removed.

I'm OK approving this PR as is, but I think we should keep #1175 open until we're able to bundle up those excessive individual log entries somehow. I'm thinking perhaps we find a way to just log "XYZ users were removed from the ABC site."?

What do you guys think?
