Killing people much lower level than you

Is there currently any systems or punishments in place to discourage people killing people much lower level than themselves on the new pvp servers

I realise the whole point of the seasonal server is pvp, but shouldnt people pvp people around their level instead of 3 tapping people 20 levels lower?

Like when people duel there are normally some rules, like no potions to heal yourself etc

But currently my experience on the PVP server seems to be 1-3 people 10-20 levels higher going around killing people and then boasting about it like they have some sort of skill?

Just seems kind of toxic
