We don't have a registration queue enabled, once a user verifies their email then their account, it is created; we rely on Stop Forum Spam only, for spam prevention (heck, it's where the SFS mod was written and tested, it replaced the need for a full admin staff of 8+ users; now we have two staffers other than myself, and they ultimately just work on community development [making new conversations], whereas before they where corralling spammers).
