Wikileaks broadcasts secret message hidden in public keys "were fine 8chan post fake"

For those not caught up, there has not been visual proof of Julian being alive since his internet was cut a month ago for a police raid on the embassy. Tweets went out showing that his deadman switch was activated. Cryptographic hashes that have never failed to match what wikileaks later releases are mismatched for the first time. Wikileaks twitter account now possibly compromised, denies anything happened to him, but refuses to provide proof of life. I am unable to tell if their official bitcoin account was compromised, only that it is being used to send a secret message a few days ago.

Results of research I put together:

2016-05-17 ---- Last expense from wikileaks account before embassy incident.

2016-11-18 ---- First send transaction after incident. Wikileaks account relocates 50 btc to a new address where it still is located.
Part of the transaction goes to another address 189o.

2016-11-18 ---- 2 minutes later, Wikileaks sends 25 separate transactions directly to the 13LB account all in a 30 minute timespan. During this time, the 189o account forwards all that it received 25 minutes earlier, also to the 13LB account.

2016-11-20 ---- 2 days after this, the 13LB account broadcasts a secret message embedded in public keys: "were fine 8chan post fake"

2016-11-24 ---- Someone notices the secret broadcast and replies "how wecan trust you" also using messages embedded in public keys, with each transaction being sent from a separate ip address over the span of 60 seconds.

UPDATE:

I may have found the 8chan post they are talking about. I do not know for sure what 8chan post this message refers to so apologies if this is an unrelated post that just happens to be related to wikileaks posted around the same time and then deleted. I am guessing 8chan is similar to 4chan in that almost nothing gets deleted, making this seem special.

Alternate possibility for the post they refer to that seems more worthy of response than the one above (there is a lot of misinformation on 8chan) :

UPDATE TWO:

The fees that were paid on the 25 rapid succession transactions were custom entered and not the default from a bitcoin client, meaning they are also broadcasted information, albeit much more cryptic... perhaps a stenographer lurks?
