Likely the private memo key as many believed that was required years ago. From what I hear, it isn't even from their account which makes it stranger.

https://steemworld.org/transfer-search?login=steemit is a nice tool!

Copying the memo keys in the original screenshot, in case anyone Googles them:

I guess we don't know for sure who sent those funds (i.e. whose exchange account initiated those transfers). But it would be really embarrassing if the administrators of the @steemit account didn't understand the difference between the transaction memo and a private memo key.

Wouldn't be shocking to me, the admins of the Steemit accounts just copy and pasted a bunch of the code from the hive fork to try to use against us lol
