Presently, it may well seem to users who are not yet familiar with MathOverflow
that flooding the site with questions is desirable and encouraged behavior --
at least this is what the point system appears to suggest:

  - an upvote on a question adds more than twice as many points as
    a downvote takes away, which can make even questions with negative score
    yield points,

  - one can get an unlimited number of points for questions, also if
    one doesn't answer any question of someone else, and

  - neither questions being closed as off-topic nor posts deleted
    for reasons of moderation nor flags "cost" any points
    (except for spam flags, but these are not applicable).

Recent examples may be [Saint Georg][1] and [Ali Sadegh Daghighi][2], who both
collected notable numbers of points within short time until their accounts
were suspended. According to the development of their score, both of them
have all the time made positive contributions to the site.

Do people see a problem here which should be addressed in some way?
