Op, should I say that your observation is true or I should go further to explain. Naturally, many people do not come here because of the passion for bitcoin. Some came here because of money and I am among those people, but as the time goes on, I recieved some high level information that made me fall in love with the forum. Now, I have passion for bitcoin. This does not mean that I will quit the forum if there's no longer signature campaign. But it means that my activity will reduce, which is what the OP is saying.
This actually reminded me of the comment a newbie made earlier last year regarding something like this too. The newbie said that he was recommended to the forum by a friend who told him he could make money from the forum. I can't remember the username of that member; otherwise, I would have checked on him or her to see if their intention of joining the forum was finally archived or not.
There are so many members on this forum, and everyone has their best interests at heart, which is why they are here. Some people are here with a sincere interest in learning about Bitcoin and blockchain technology; some people are here to learn trading; some people came to the forum due to the issues they were faced with in the crypto space; and some people are also here because they want to see the community grow. Everyone has a reason why they are here, and I feel it's normal; there's no way everyone can have the same aims and desires. The forum is a public community for anyone, but it's against those who break its rules.
Also, the forum is not a place to rely on for only signature payments; there's life off the forum, and no one should handle their earnings here as real employment; it's just my two cents.
