The proposal is: to prohibit (may be programmatically) creating more than one topic in one section in one month.
Reason: some sections are occupied by the same authors. Authors abuse the ability to create new topics.
Examples:
https://bitcointalk.org/index.php?board=128.0
https://bitcointalk.org/index.php?board=91.0

As an alternative: make it possible to create a new topic after receiving 10 new merits
