Danny's list started as a list of people whose arguments he couldn't refute, so he started advocating ignoring them as a signature spammers. The best example is MPOE-PR who never participated in any paid signature campaign but mercilessly  and very skillfully poked fun at some of Danny's arguments. Anyone ignoring MPOE-PR would miss some of the best satirical and critical writing on Bitcointalk, although the account is no longer active.

The list also includes me and several other long time members who had poked fun at Danny and other former stalwarts turned later scammers like DeathAndTaxes.

The list may be statistically correct, i.e. the majority of the names on the list are or were wearing paid signatures and spamming them. But the list also includes multiple people involved in scam busting. And therefore becomes a danger to the newcomers who won't be able to see the warning and explanations of the old scams.

About the latter additions I have nothing to say, neither positive or negative, I wasn't really paying attention. I'm mostly interested in scams not spam.
