That’s wrong, even if some folks do.
If you filter 2002::/16, peer to peer that still uses 6to4 get broken -> more calls to the help desk. The only that IETF did is to deprecate 6to4 anycast (RFC7526), so only the IPv4 anycast prefix is not anymore working. Maybe the right thing to filter is then 192.88.99.1. This is the relevant text: 4. Deprecation This document formally deprecates the anycast 6to4 transition mechanism defined in [RFC3068] and the associated anycast IPv4 address 192.88.99.1. It is no longer considered to be a useful service of last resort. The prefix 192.88.99.0/24 MUST NOT be reassigned for other use except by a future IETF Standards Action. The basic unicast 6to4 mechanism defined in [RFC3056] and the associated 6to4 IPv6 prefix 2002::/16 are not deprecated. The default address selection rules specified in [RFC6724] are not modified. In the absence of 6to4 anycast, "6to4 Provider Managed Tunnels" [RFC6732] will no longer be necessary, so they are also deprecated by this document.

Has it been cleaned up?
