What's your favorite “abandoned rule”? has been closed then deleted and undeleted.
Can it be given a historical lock as well?
None of those answers are useful or contribute anything worthwhile to the programming community.
People do a perfectly fine job of figuring out on their own which rules to violate, and there are few if any of the existing answers that provide any sort of justification for their encouraged violation of stated rule.
This definitely falls in the "bad question" category, a good example of why we don't allow these types of questions to exist anymore. I'm a fan of only keeping around those rare exceptions, the questions that defied all expectations and attracted good, useful answers despite being in poor form. This ain't one.
Besides, the purpose of the historical lock is to preserve specific questions of historical interest. If we start applying it indiscriminately to all old questions, it begins to lose its merit. Sometimes we really do need to just let the bad questions die.
