Had a heated argument over how constant pks would affect streamers. However, in the lengthy and somewhat meaningless argument, i did get a pretty good solution to the problem, that I admit, is far less intrusive and more acceptable than the ones i proposed. The idea is to re-spawn players randomly on the world after they are killed. This would prevent mass griefing as it would be difficult to traverse a large distance in this game, especially at lower levels.
Sure it might be annoying to get tped elsewhere while ur in the middle of a quest, but as long as the region ur tped to has relevant quests for ur level, it isn't as much of an issue.
I don't know if this has already been implemented, but if it hasn't yet been done, then hey, at least my time wasn't wasted but if it is, then great, now i know.
If u want to read the mess, here u go:

A system similar to this exists where the corrupt player is tped instead. Just a slight addition where players that assist the pk also gain corruption will solve the problem as then multiple players will be tped at once if they gang up on someone. (Note: It should take something like 2 or 3 pk assists to gain the corruption level of an actual pk)
