I think the Signature campaign that he means was like those paid in BTC Like those in the Bitcointalk forum. Because as far as I know there is nothing here in the AltcoinsTalk forum as of now. But I believe soon it will because the AltcoinsTalk forum was rapidly growing and with the right promotion and giveaways I'm sure it will be achieved soon.
Aha, I know of some projects that used to run bounty & pay with ETH as IoTex & Ludena Protocol. The rest are only paid by stake, then converted to the project token.
If topic owner wants signature campaigns directly paid by ETH/BTC like on BitcoinTalk then I think he will have to wait for more time.
BitcoinTalk currently has 223K hits per day, while Altcoinstalks only has 3.4K hits per day. 65 vs 1!
So there will be no projects really interested in AltcoinsTalks, at least in the short term.
I think the Admin will not have a plan for this either, which will make members tend to spam & abuse the forum instead of contributing to the crypto community.
