Raping eq and/or owning areas seems to be problem. One way is just prevent
player to do or go to area or mob or make mob hard to kill. Other way is make
player not to want to go near that particular.

So problematic mobs could have list of players which have killed it within
certain time period and/or number of times it's been killed by particular
player. If player is on those lists mob could cast some nastities on that
particular player like disintegrate, destroy armor, entropy or other nastity
which really hurts player and it doesn't normally do.

Not at any random target, but just that particular player. Not nice, but
thats not intention, as idea is to keep player away from mob or area to give
chance to others at it. If that kind of prot were made a piece of code to
freely inserted in any mob which seems to be needing it, everyone wouln't need
to invent new rapeprot to every single mob. Ofcourse it's much nicer to have
special prot on special mob.

Downside to that is that kind of prot might make hard do long eq runs with
intention of something to everyone (in party).
