I don’t see it that way, you can have more reliable members in the subscription campaign, you can have members with higher post quality and merits in your subscription campaign and even then your subscription campaign doesn’t have good results and ends in just 1 week. The question has always been:
To what extent do signature campaign participants use the services they advertise?
That is indeed the biggest criteria for me too. You can have 10 super good posters who never even use the services,,, then this only means you get good visibility in the forum but not necessary, people who actually use them.
Or you have 20 normal users but who also use the product/service, then you have ambassadors who talk about your service AND can advice and help others use it. Without utility, there is no long term success. This is true for any crypto service.
