Two in a row.
Edit: Actually, leaving this conversation as it is, suddenly bringing it into PMs, will only cause more confusion. I'll be clear as best I can.
What I mean is that the only way the Yliakum races could avoid terran names was if they knew them. Most of them have, as far as I can tell, the same lips and vocal chords that we do, so similar sounds would evolve. From those similar sounds, words and names that are easy to say would also evolve; likely in a similar way to terran speech. Even if they evolved those words and names very differently, they would still use at least some terran names by pure chance. You could say that although it's annoying (ref. that comic) when everyone obviously copies their name from something else, it's also annoying when any old string of letters is used except "normal" ones. One's mental eyes are drawn to the empty space.
As for rules, no mod should demand that a name be changed just because it reminds them of something or someone, or strikes them as "normal". The reason for the change would need to be based on how the player involved uses the name.
