Yes, that's true, because despite the fact Chartbuddy is said to make the most post daily, his posts are all kind of similar, and not only that but 99.9% of his posts are centered on a single board on the forum, which is the "Speculation" board, as he seems to be an active contributor there, than any part of the forum. But however, if O.P who happens to be a representative of a crypto gambling casino is okay having his signature been display on only one side of the forum (i.e Speculation) then Chartbuddy is the surest person for the job.
Signature is disabled on the WO thread and Buddy only post there.
He's more like a secretary that give update only on Bitcoin prices.
Well I guess that's why campaign managers are needed
You selected only individuals and a bot that have never posted in the Gambling board
Not to mention like has been said before more than half of your mentioned don't wear any signature for campaigns.
