The moderator could create a thread for the express purpose of making an announcement. The thread could then be locked to prevent people from replying to it. Lots of forums have "sticky" threads along these lines.

Hi All, Just a reminder that we do not allow political topics on our forum. Experience has taught us that these kinds of discussions lead to bad feelings and personal attacks.Back in August, we posted a message outlining our policy of not allowing discussions about the Voice referendum as we considered this to be a political issue (here’s a link to that message for reference: https://thegreynomads.activeboard.com/t69792887/a-voice-thread-has-been-removed/). Although I understand that some members may be keen to talk about the outcome of the referendum, this forum is not the platform to have that discussion. We created this forum to be an inclusive and positive place for members to discuss the grey nomad lifestyle and although we now have subforums where people can discuss other issues, we would like politics to be avoided. Thanks for your understanding.
