These are definitely bogons and I recall that CESNET had similar issues,
that is announcing weird prefixes, before...

Why these are definitely bogons:
http://www.iana.org/assignments/ipv6-address-space

1000::/4              Reserved by IETF        [RFC3513]

Thus no 1xxx possible.

GRH gets it directly from AS3257 thus that they are transitting makes
sense then. Now lets wonder why 2852 is announcing it

Only 20 people pass it on out of about 80+ active GRH peers, thank you
deer filters ;)
