So sometimes when asking for help people fall pray to what killed you. Maybe a tag like this would be cool.

MOB - Any living entities with mob style tag.
TRAP - Any block or such thing.
PK - A another user killed you.
UNK - Anything that did not get registered correctly.

It would read

USERNAME is bleeding... - Possible reason - PK

Added your suggestion to my todo list. I don't know when I will find time to work on PlayerRevive. There are many requests and I will do them all once I have the time.

Thank you <3
