This discussion is related to the
Quotes addon.
I believe there might be an issue with quoting and linking to usernames if the username has a space. In the example below the only difference in the formatted HTML is that one user has a space, and the other doesnt, making the two quotations end up getting styled very differently.

The username "(. )( .)" sans quotes also makes the yellowish quote box.
If you don't use either of those features, admins can create accounts with hyphens, which is probably a bug.
