What is the exact meaning of `known_producers` returned by the RPC `network_info` call

By doing and RPC call with network_info I can get my peers and something called known_producers.

Call and parsing

http post http://127.0.0.1:3030 jsonrpc=2.0 method=network_info params:='[]' id=dontcare | node parse-network-info.js

If I parse the resultings data with my script, I can find which of muy peers are NOT in the known_producers set:

Questions:

That means that those nodes are not producing any chunks and so are interfering with the known producers peers ?
Should/coluld I blacklist them so they don't generate extra traffic to my node ?
What is the blacklisting format ? See issue #83
Is it better to use a "whitelist" with known producers rather than blacklisting ?

Thanks !
