Guess the title says it, can we have a true talk without it for the sake of it about Bitcoin? Not like you're paid to say something.
Yes mate there is some social media platform such as reddit, twitter, telegram and etc. You could discuss there without any post incentive or annoying signature. But we cant fan out it on forum cause its always here. Probably out of 10 people maybe only 99% is only one there not wearing signature and posting his opinion.
Signature campaign is here for a reason and not to sugarcoat money related. But it is one way to make the forum be more attractive place for discussion.
