This is a loser strategy, no real big money in that way.
Unless you're a Hero member or above, signature campaign pays really well IMO even if I'm just a full member. But there are endless ways of earning money in different fields, but I can't talk about that since it's mentioned that it's limited on bitcointalk only. Most of the things that can make you earn money in this forum is done digital, of course. Digital Goods, Services, Loans, etc -- All of these would require effort and knowledge. So basically, to earn money in here, you have to be knowledgeable about something.
I'm also a newbie and thank you for the idea you've shared. yes, and i do know that payouts are depending on how high your rank is. The higher the better. Just follow the rules and never ever violate against their policy or terms.
