Well, I can think of ways to avoid the whole thing other than "don't die." Problem is, are those alternatives worth the extra effort of avoiding a curse from a skeleton you can't bury the remains of?
Though that people do have souvenirs of all their kills, or just collections of bodies, one would think they could be flagged as legacy bodies much like clothing and many other things have been recently, thus making them useless for witchcraft. Then again, it could be worth the tears of seeing those that have died and inherited getting cursed, even if it occurred a week after the server started. Much drama would definitely be had.
