I’m not sure it’s a bug or it’s a feature. Let’s assume this:
1. We have a topic that’s one year (or more) old.
- Someone add a comment to that topic;
- The topic will come first on the homepage (this is good);
- That comment is spam/offtopic/whatever. So it is deleted;
- The topic remains on the homepage, although it doesn’t have anything new.
I believe that after step `4` the topic should go away from the main page?

I believe this is the same as:
> [@Deleting posts doesn't reset last activity date](https://meta.discourse.org/t/deleting-posts-doesnt-reset-last-activity-date/31348):

> We were having an issue with the auto-close feature where threads which have been dormant for a while weren’t being closed automatically (we have it set to close 30 days after the last activity). Doing some moderating, I have found that deleting the last post in a thread doesn’t reset the last activity date on the thread. So if a spammer wannabe comes in and lays down a crap post two months after the last post, we lose those two months for the auto-close functionality to work. Edit: It seems…
