Removing a spam necropost leaves the thread at the top

Here's something I've been noticing:

If a spambot bumps an old thread and the bot post is removed, then that thread continues to be listed as a current one at https://www.linuxquestions.org/questions/ for a while, even though opening that thread shows no new posts.

That's obviously what happened here:

https://www.linuxquestions.org/quest...5/#post6141573

That's because regular members have new posts.

Truthfully if it was just a post of "Spam. Reported" I typically remove the regular member's post figuring that they'd not be offended.

In this case, the spam was a later edit, and others replied with answers.

Unfortunately there's no, "one size fits all", mold here.

I have seen this behavior on other forum software (with and without the additional posts). I suspect it is a deep-rooted problem with file timestamps, probably not easy to "fix".

Simple solution is to lock old threads. jeremy says no, so it ain't gunna happen.

End of discussion.
