Forbidden

 Previously, we forbade any mention of the thing that is forbidden to mention.

This led to a problem with juridical texts that referenced the forbidden subject. While some were burned to rectify their breach of the law, others were redacted quickly enough to be permitted to remain.

There is now not a single mention of the outlawed subject in any of the books defining the law.

This of course has certain unintended effects, as we now cannot refer directly to it.

However nothing could possibly stop us from taking the required and inevitable next step:

Now, the thing that was previously forbidden to mention has become forbidden to do.

Hence, this announcement to all those living within our borders: don't engage in the prohibited act. Not knowing which act is forbidden just because it wasn't mentioned is no legal excuse.

Stay vigilant and avoid any involvement in this prohibited activity.

And should you witness it. Or even suspect such activity to take place. You are duly obligated to report it to the proper authorities but remember that you must not mention or even imply the nature of the reported activities while so doing.
