Assuming this is a serious question:

1. comp.lang.python has relatively little spam, compared to others.

2. The spam posters aren't looking for responses within the individual NGs, 
they're just hoping you'll click through to the link within the post. It's a 
version of "fire and forget"

3. Simple keyword filtering /by whom/? There is no central NG governing 
authority.

The best response is to ignore[1] the spam posts; they'll eventually expire 
and disappear from your newsreader.

[1] Although if they're egregiously stupid, you may find yourself mocking 
the OP. Realize that as witty and urbane as your response may be, the OP 
ain't listening. :-)
