tl;dr
I'll admit I don't know exactly how 4chan works but this is how I believe it goes:
Each board has a limit to the number of threads, what that number is depends on the board, to keep the example simple I'll use 10. When 10 threads are posted, an new thread will cause one of the old threads to be deleted to make room. The thread that gets deleted will be the oldest one created, ie. the one the oldest first post. This is why bumping a thread won't make it last longer, because time it was created is still the same. That post gets tagged with "Marked for deleton (old)" to let people know it will be deleted when a new post is made. Now, should one of the other threads be deleted for a reason other than a new thread being made (such as mod deletion) then there will be only 9 threads on the board, which means a new thread could be posted without needing to delete the oldest thread. When that happens then oldest thread should no longer be tagged with "Marked for deletion (old)". This means that the only thing that make threads "expire" are the creation of new threads when the thread limit is reached, which is pretty much all the time unless something like a mod wipe happens. This also means that stupid threads like requests and failed replies both bump off good threads and waste space.
Because I'm a loser that spends too much time on 4chan, I've noticed this happen.
