Hello,
This is Yuji Sekiya, WIDE Project.

No, Hank might mean both of 2001:200::/32 and 2001:200::/35 prefixes are
advertised from AS1752(BT). The prefixes are ours and AS1752 should
not originate the prefixes. 

I can see there bugos prefixes on the below looking glass.

If AS1752 advertises the prefixes, please stop it.
