The newbies are less problematic than the jr. members. Usually the minimum required rank (e.g. sig. campaign) is jr. member. Bounties often have Google forms, and this can get attacked/abused easily when applying. A recent case that I've reported to a moderator was ~50 jr. members applying within 30 minutes (all the classic spam accounts). Merit requirement needs to be added for this rank, and it should be a tad more than 1 merit.
