I really feel posters need protecting. I don't know if writing at the end of the first post a statement saying you don't give permission for it to be shared anywhere would help?
Goodness, how naive you are!
No of course this won't make any difference.
You should read the terms of usage of Mumsnet (scroll right down to the very bottom of the screen if you're on a laptop/PC). But this in particular:
We may now or in the future permit users to post, upload, transmit through, or otherwise make available on the site (collectively, "submit") messages, recipes, text, illustrations, files, images, graphics, photos, comments, sounds, music, videos, information, content, and/or other materials ("User Content"). We have the right to publish, edit or reject any User Content that you send us either via email, via the site or in writing via post for any purpose whatsoever, commercial or otherwise, without payment to you - unless we have specifically agreed otherwise in writing prior to submission
By submitting User Content to us, simultaneously with such posting you automatically grant to us a worldwide, fully-paid, royalty-free, perpetual, irrevocable, non-exclusive, fully sublicensable, and transferable right and license to use, record, sell, lease, reproduce, distribute, create derivative works based upon (including, without limitation, translations), publicly display, publicly perform, transmit, publish and otherwise exploit the User Content (in whole or in part) as Mumsnet, in its sole discretion, deems appropriate. We may exercise this grant in any format, media or technology now known or later developed for the full term of any copyright that may exist in such User Content
It's not just other media but Mumsnet themselves have the right to use anything you've posted too.
It's a huge mistake to think that this is a private or safe space
