AS 3356 (Level 3) -- Community 3356:666

["Sriram, Kotikalapudi \(Fed\) via NANOG" <nanog () nanog org>]

There is an old NANOG thread from 2005 that said AS 3356 (Level 3) were applying 3356:666 to indicate Peer route:
https://archive.nanog.org/mailinglist/mailarchives/old_archive/2005-12/msg00280.html
Also, see: https://onestep.net/communities/as3356/ 

Now network operators commonly use ASN:666 for BGP Blackholing Community.
(ASN = the operator's AS number)
See, for example, https://www.he.net/adm/blackhole.html 

Does anyone know if AS 3356 has changed how it uses 3356:666?
I.e., is it known if they now use it for Blackholing Community? 

Thank you.
