Snow Angel of AQW GD/Q&A/Guides
In the top right, above the list of threads, there is a thing that says "Display Topics from Last" with a dropdown menu next to it. The default is probably 7 days, but you can change it to All Topics. You'll be able to see things that haven't been purged, which is basically FAQ tagged threads. Normal threads that aren't FAQed will get purged after a certain amount of time (see below), so any posts that are in those threads will be deleted.
I went and looked and assuming it's still accurate, the AQGD is set for this:
Threads that have been inactive for 15+ days and have less than 15 replies will be purged
Threads that have been inactive for 30+ days and have less than 40 replies will be purged
Threads that have been inactive for 45+ days will be purged regardless of the number of replies
