(This is retroactive; existing comments are also just first names. I'm also still happy to make custom changes for people, like skipping your posts entirely, using initials, or using a nickname.)
 One fix would be to dynamically add last initials if needed for disambiguation. This is a little tricky, as it requires a pass over all the names before you can choose how to display each, but I could do that if things become too confusing.
