Hi Denise,
I love how you are thinking about the community as you drift off to sleep 🙂
So, to answer your question, in the most part we do not remove posts from members from the community (you can find posts dating back to 2006). There are occasions where we remove company posts because they are no longer relevant, there have been one or two times where we have had to delete some content as they were infringing on our terms and conditions and we've also, at the request of members, removed some of their posts.
I'm sure at some point in the future we'll have to have a clear out, but for now the posts are there and in all their glory for existing and new members to look through.
Kindest regards,
Julia
