Such things may happen when using an experimental validator that checks 
against some unspecified document that may and probably will change 
daily. But in this case, this must be a temporary bug caused by some 
update gone wrong:

The "robots" keyword has been in the WHATWG Wiki for a long time, it has 
reasonably good documentation, and it is wildly used, so it is difficult 
to see why it would have been intentionally removed from the set of 
keywords accepted by the validator.

Moreover, http://www.validator.nu accepts it, as before.

That's OK. Completely redundant (it just states the default), but valid.

No. It's not there at all, really, except indirectly via a reference to 
the WHATWG Wiki. And no change in the reference, or the referenced 
document in this matter.

Must be.
