I can't recall which anon noticed the 300 on the door so apologies for not giving credit. There's a pretty strong link to the message in drop 300 and recent events with Lynn de Rothschild (a.k.a "L", a.k.a "LDR").

EDIT: credit to u/Speakfree

u/#q300

So here in drop 300 we have a message to LDR to "Not come here again". Not sure exactly where "here" is but when linked up to recent articles about LDR from just a couple of days ago, she's apparently planning to return to the United States.

Also I took a detour and replaced Alwaleed with LDR and dug up some connections to LDR and Clinton and she was apparently very tightly involved in Hillary's candidacy, to the level of giving campaign and policy advice (foreign interference?).

If any anons want to browse her comms with Hillary:

Here's her donations (326 of 'em under this name):

There are some weird patterns to her donations. $789, $818, and $1791 show up a lot, for instance.
