It's fairly common for vandals/inexperienced test editors to blank pages, e.g. here. This isn't normally a problem because it's easily/quickly reverted, but I've been getting "topic archived" notifications from it, which makes it a lot more annoying. I'd like to see the system improved so that these distractions go away.

Do you want to get notifications when any subscribed discussions are removed from the talk page, or are you hoping that they can distinguish between blanking and true archiving?
I don't want to be getting notifications for test/vandalism blanking.
If you are willing to give up notifications for true archiving as well, then you can turn off all notifications related to talk page archiving at https://en.wikipedia.org/wiki/Special:Preferences#mw-prefsection-echo
