Some questions:

1) On what grounds, exactly, is a host added to this list?
2) Who is able to edit the contents of the list?
3) How often are hosts on this list re-evaluated against the conditions
set in point 1?
4) What exactly are "names and IPs that you don't want to be on a
blacklist" ?
5) In your documentation at the URL above you state "127.0.0.3 =
yellowlisted - mixed source - do not blacklist or whitelist". Yet here
you've said, of hosts that should never be blacklisted, "some from my
yellow list", which is correct?


I find myself confused by your arbitrary terminology.
