When I was pking for the leaderboard a few seasons ago, I noticed alot of Brazilians hosting organized boost sessions (specifically players named Matt and Mario who ended up placing in #4 and #5 right after me). They would go find a place secluded and which had pks enabled and start a mob to boost their pks. It was a huge problem to all the other legit pkers who were going for the top of the leaderboard. Many and many of the times that admins found these places they only warped the Brazilians or disabled pks and the Brazilians would just move to another spot. Me and the #1 dude Ice reported constantly to admins mainly Glitch about this. Glitch ended up helping us get some of the Brazilians banned. I don't think many pkers know about this since they were good at hiding it or doing it in really secluded places. The dude who placed #5, Matt, ended up getting his 130k or so pks completely reset after getting caught boosting. I'd say this new system they got going would definitely help for situations like these. At the same time, not counting pks after killing the same person in a tower really does suck as stated before. They should just turn off this system inside towers as it really has no positive effects. Leaving it on in the overworld and buildings like the summer house, mini golf area, and snow arena (one of the most used spots for those boosting Brazilians) seems fine to me though.
