Does Tunnelbroker block fd00::/48 (IPv6 unique local addresses) from/to me via my tunnel?

As you point out, these are local addresses, so how would they ever end up on your tunnel?

jea101

My router doesn't currently block anything outgoing IPv6 so
fd00::/48 outbound is permitted by my router.

cholzhauer

You're missing my point. As you mentioned, these are link local, meaning they are relegated to staying inside your network. Even if your router passes them, other routers will drop them as they should not see this traffic

jea101

I agree that other routers should reject (preferred) or drop them.

FYI: Link local are fe80::/10 – not fd

You're right, thanks for correcting me.

My point still stands though, and in the last post, you acknowledge it, unless you meant my screwup of FE80.

The addresses you ask about are equivalent to RFC1918 addresses in IPv4, thus even if you pass them, HE won't.
