PvP out of hand

Actually this is about the new pvp area

Many complaints of ridiculously pointless (and suspicious) kills near spawn have been reported (Ok i admit it before anybody else does it for me, i did kill some players with no items just for fun, but hey its pvp) and it has clearly gotten out of hand, such as people being stupid and knocking people into lava just to kill them again and call them weaklings and other similar issues that involve trolling

I'll update this later as i go on the server again and see whats changed and whats caught on and i'll see if i can request a solution based on how its doing, and perhaps this will be fixed once factions are on?

I've seen that many itemless players get ridiculous knockback combos, and thus explains the abuse of this, perhaps the critical hit combo is too high or its pure hacks. but something needs to be done about this since us players who worked for their inventory die from falling off ledges by these strange knockback streaks, and go to see them use their items when they arent sure if its just the server or hacks. I am aware that the lava is gone and i appreciate that

Understand how this could be very annoying, and may i suggest if you see this offer to help guide them. Because as a pvp server this is expected. Some of the more powerfull players should make friends with the new guys, potentially can be your new ally, friend, or even become an enemy. But at least you did your best to be nice person.
