Is kiting ok in PKing?

I remembered ranger pures from back in the day of original RuneScape so levelled to 40 range and checked out the wilderness on a PK world. Fought a dude who was clearly a STR pure so I backed off and kept sticking and moving so he couldn’t hit me as often. He called me a noob and said I was a “safe runner”. Am I meant to just stand and bang and hope for the best? Is movement frowned upon or something?
