Yea, but you shouldn't be in a person's server if they do that anyway. That's like jumping off a cliff because a creep followed you, just punch the sucka in the face (Prob. solved :D)
That brown townogy doesn't make any sense at all.
To determine if an admin will abuse this, and thus, avoid his server, you either have to experience it, or hear from someone who has experienced it. Either way, that admin has utilized this mod to detract from someone's gameplay experience.
Now consider how easy this mod is to abuse beside how often a situation occurs where killing the player is by far the best solution. The cons outweigh the pros. Blockland is better off without force kill.
