I know that the question ban formula of stack exchange is very secret and it's not revealed in public. But since stack exchange is run by the community, someone must know it. So who is the formula revealed to? Do you need to reach a certain reputation level so you are recognized as a trusted member and then the formula is revealed?
Only the Stack Exchange developers (and perhaps a handful Community Managers) know this. It's coded into the system, and perhaps documented in an internal document, but no amount of reputation will reveal this information. If that would be the case, I'm sure somebody would have leaked it by now.
Really smart people like @rene were able to reverse engineer part of it, resulting in this SEDE query, but it's by no means official.
