If we try to make a rational justification for the decision it means that the decision is rational. If the justification doesn't hold, we'll make another irrational decision and after that will try to justify it rationally.

The internet is different than all information media we had until now (books, newspapers, tv):
1. the information remains there for a very long time
2. it's very easy to search and to share the the information
3. usually the information is not edited by a group with some social responsibilities

So, I think that we need some new rules for publishing information on the internet.
