If You are going to start & keep large threads with multiple links

YOU should make sure on a regular basis:

(1)  that ALL links are still ACTIVE

(2)  Remove or re-up any Dead links  ASAP

(3)  Keep All Preview Pictures Active

(4)  Basically Keep the THREAD well maintained

This will make the Moderating teams Job that little bit easier

If a large thread is NOT well Maintained

Then it runs a very big risk of DELETION
