As trynewideas says, “Wi” was the name of the player who famously described this problem. Source: I worked for Turbine at the time.

From what I recall it was a character named Wi who was persistently vocal about it.

This is the correct answer. Wi was a prolific blogger and fun personality.

would love to know how “bad” Wi's hash actually was, like what percentile of the users DB sorted higher/lower than it

One of the impacted players had an in-game character named Wi.
