namecoind rejects works

[questionstorm]

Why does namecoind do this?

Code:

I think I should see nothing here but not rejected works.  It's just
pure curiosity but I want to know what went wrong here.  It is a
cgminer pointed to my namecoind (port 8336).

Mining with a CPU, really? You will never find a block, moreover NMC's value is so low. Basically, the difficulty is so high, thats why you are getting rejected shares.

Give up, you are wasting electricity.
