Are current players taken into account when mods review apps for characters from different versions that are very similar?

For example, if someone plays Character A, and somebody else apps Character B from a universe where everything is the same except A and B are married, Player A may not be okay with that. Or another example, if somebody is playing a game transplant AU of Character A, and somebody else apps OU Character A, in the case of most games, two people would now be playing basically the same character.
