		  fine if not - but falsey values are problematic and is
		  non-ideal. More importantly, list=blocks won't indicate if a
		  non-blocked user is blocked then unblocked. This should be
		  exceedingy rare, but regardless, we thus need to check
		  list=logevents, which has a nicely updating logid
		  parameter. We can't rely just on that, though, since it
		  doesn't account for blocks that have expired on their own.

		  As such, we use both. Using some ternaries, the logid
		  variables are false if there's no logevents, so if they
		  aren't equal we defintely have a changed entry (send
		  confirmation). If they are equal, then either the user was
		  never blocked (the block statuses will be equal, no
		  confirmation) or there's no new block, in which case either
		  a block expired (different statuses, confirmation) or the
		  same block is still active (same status, no confirmation).
