Note: This answer is in regards to comments, please ignore it.
This is not a bug technically. It is [by-design]

There are some rules, of course:
- This only works when referring to other people who have already commented.
2. Your comment must include @username that you are referring to, where “username” is a reasonable match to the user’s current display name (as seen in the comments above yours).
3. There must be a starts-with, case insensitive match of at least THREE characters to the displayname. So @a and @ab will never match anyone or anything.
4. Spaces are ignored in the match, so if the person’s display name is “Peter Smith” then just use @peter to match, or @petersmith.
5. Matching is performed in reverse chronological order, so if there are five people named “John” in the comments, writing “hey @john, have you considered apples?” will match the most recent John to comment.
6. Only one person can be replied to at a time in a comment. The first one in the string wins.
7. Users who have no display name set, whose faux-displayname is derived from their OpenID URL, cannot be matched.
Have a look at the rules I bolded.
So, to match your old name, "jsbangs
" would have worked.
