A question came up with a mass number of answers that are all repeats of earlier answers, and some even spam linking to other game-answer sites: What is the meaning of the Black Ops "Ascension" numbers.
Should we be counteracting this low-rep user posts with more than just down-votes and flagging? Moderator attention and 'protecting' a question (preventing users with low rep from answering) are options but may in the long run start to swamp moderators as gaming.stackexchange gets more popular and this issue pops up more.
Would an automatic 'protection' mechanism like preventing all users with reputation less than 10-50 from answering questions solve the problem, meaning a new user will have to submit one or two good questions before being able to answer any?
EDIT: I just saw that some posts are flagged as low-quality, not sure how much that tackles this problem but include it in your discussion if you think it's relevant.
