Any way to revert back to the last updated timeframe?

Hi MN Admins,

Something I've been wondering about and you might be able to advise.

The thread I've pasted the link to below had some sort of update/post made to it today which you subsequently removed because it was breaking the post guidelines.
https://www.mumsnet.com/talk/teenagers/4837256-where-can-i-buy-this-tshirt

It showed up in the list of "Threads I'm On" as a recently active thread, because I did post on it, but the last actual valid post of the thread was back in June 2023.

My question is this - if MN Admins remove a post and it's the last post on the thread (as per this case), would it be possible to revert the last modified date back to the last valid post, thereby leaving the post in the list of all that made valid posts to it, in their list of threads from June 2023 instead of September 2023?

Does the above make sense?

Hi OP

Thanks so much for the suggestion - we'll discuss this in the office.

I don't know why threads aren't just locked after a month of inactivity.

I'd be happy with inactivity of 3 months (allows for people to go on holidays etc and return back to update if they wanted) and then lock the thread. Don't delete it, just lock it.
Then if someone returns after 4 months or whatever, they can copy the link to the old thread, include it in the first post of the new thread and Bob's your uncle! Job done.
