Currently any banned addon in a debug log results in a bug report being marked invalid, but there's no indication of which addons in the log are banned.
By reporting issues we're trying to help - make it easier for us to comply with this requirement by listing which addons in the debug log are banned - that way we'll be able to remove the offender quickly and update the bug report, rather than the current situation where we have to examine a list (that we may not be able to find quickly) and then painfully identify any offenders.
