Hi @Helloise - unfortunately not.

The Trending box is algorithm-based, meaning it shows the top most-viewed threads at any point in time. We can't tailor it to hide specific topics, though we are able to exclude individual threads if they're particularly sensitive ones.

Hi @Helloise please access this link where you can choose which topics you'd prefer to hide: www.mumsnet.com/Talk/topic-choice

Hope this helps, and give us a shout if you need any more help with anything.
