-/// (Desperate, best-effort) attempt to get the user that pinned the last message
-///
-/// Now, since Discord is SUPER annoying, it doesn't actually tell you which bloody user
-/// that triggered the pins update event. So, you have to dig into the audit log.
-/// Unfortunately, while you do get a timestamp, the REST API does not return the time at
-/// which each action is logged, which, to me, means that it is not a freaking log *at all*.
-///
-/// I love Discord.
-///
-/// So, the plan is that only the first pinned message gets clear pinner information,
-/// since we can just get the latest pin, which should happen on the exact second.
-/// We can't reliably say the same for any existing pins, so we can only /shrug and say
-/// *somebody* did it. Ugh.
