Such mechanisms do exist, just as they do for the creation of that "punishment". The mechanisms are ad hoc, mutable, and social in nature, however. They are not set in stone, explained in detail in a site use license, or otherwise strictly codified. That is, I think, appropriate for a website devoted to a community effort with an open source modus operandi.

The key item to consider, here, is that nobody's natural rights are being violated. The rest is just flavoring. I happen to very much like the "flavor" of PerlMonks.
