My post was intended for all the ranks in general and not just legendary. Take this member for instance:
https://bitcointalk.org/index.php?action=profile;u=1777865 his post quality is way better than most of the legendaries with high merits. He has received just 1 merit... This is exactly what I'm trying to address here. Having great quality posts doesn't necessarily mean you'd have high merits.
That's fair. As you say, his post quality is way above the usual spammer, and I don't think he would have any trouble earning some merits if he stopped shilling whatever the hell "Zeitcoin" is in every post.
However, I still think we need to address higher ranked spammers in one way or another.
