On my account page, I had myself listed as a developer for fluxbox with the committer name set to "markt". Some time in the future, we switched from svn to git, and my new commits started showing up as "Mark Tiefenbruck", so I created an alias in the fluxbox project that pointed markt to "Mark Tiefenbruck". As a result, poor old mark-t, with developer next to his name, was stuck down at the bottom of the list with 0 commits. Clearly, this is not the expected behavior, since anybody can make an alias but only I can change my account page.
Further, since I didn't notice this for quite a long time, "Mark Tiefenbruck" acquired 8 kudos, while mark-t, stuck on the third page, only acquired 5. When I fixed the committer name in my account, "Mark Tiefenbruck"'s kudo rank dropped to 5, which is also not expected. It seems to have since been restored to 8, but at the time it was somewhat annoying, despite being fairly meaningless.
