We could simply ask the administrators, but, just for fun, we could program an algorithm such as the following :
<span style="color:#323232;">#1 get(the_latest_post, from_the_server)
</span><span style="color:#323232;">#2 modify its address by adding a small fixed number
</span><span style="color:#323232;">(manually adjust this small number to get one of the next posts before they can be deleted)
</span><span style="color:#323232;">#3 get(this_next_post, from_the_server)
</span>
Repeating these steps a few times and keeping statistics should allow to answer experimentally the question 😋
