I compete and am a CBJ. My preference for a comp is that both lists are shown.
The other teams list so I know whom I'm up against, and to see if friends from farther away might be there.
When I judge, having a posted and current, judge list is important to me. Not for who's on it, but that I was accepted to be a judge. With comps that more judges try to get in than can get on, it lets me know I'm there. It is very frustrating as more promoters (here in CA) don't post judge sign-up sheets, but only seem to work from personal emails to them, and then don't list who they've selected.
Teams don't know who judges them, and judges don't know the teams they've tasted.
Having the names of both really doesn't matter.
