In the specific case of "I WILL KILL YOUR ENTIRE FAMILY GO TO HELL YOU SON OF A B*TCH 9-YEAR-OLD INBRED!!!!!", I agree that warnings and block notifications are not necessary, and that removing the message with a reason, and blocking with a reason is sufficient.

However, if there was a discussion leading up to that comment, it may be useful to end the thread with a "This user has been blocked for this comment." message, so that anyone reading the discussion in future will know the outcome. (Be it them, you, other admins, other users, or Wikia Staff)

edit: I only mean a factual, neutral, informative message, and not a "I'm blocking you now, bye bye." type message.
