It's to prevent revivals of discussions where the information involved is outdated.

For example, on the 29th of September (I believe this is the rule break David is referring to), you responded to a query made in Jan 2014, almost 2 years ago, where the question was whether you can link attack with an Item and Monster, while there was a Center Monster on your field.

Back then, it was illegal as there was no Monsters or Items that allowed such a thing. Now it is legal as some cards permit that.
