Many mailing lists out there require subscription before posting to reduce spam. Most GNU mailing lists, including I believe gcc-help, do NOT require subscription before posting. We have a very nice system for handling spam to our mailing lists and the GNU developers are quite willing to deal with the remaining moderation duties. On the other hand having extraneous bugs filed by spammers and having spam comments added to existing bugs in Bugzilla is a far larger PITA to handle than moderating a mailing list. Bugzilla has no facility for "moderating" bug comments or new bugs so that they can be rejected before being accepted if they're deemed to be spam. Instead the cleanup has to come afterwards, and Bugzilla (like most bug trackers) does not have great facilities for deleting bug reports and comments once created (after all normally you wouldn't want to do this). Requiring an account for bug reports alleviates this problem. It also helps with quality since it ensures we can reach you if we need more information, and that you are notified of activity on the bug and can respond. Cheers!
