You have a signature campaign running on your profile, right now.
At the same time you are calling them useless. The hypocrisy or at least inconsistency is entertaining.

You claim they are useless, but I bet you can name almost every company that runs a signature campaign around here (assuming you spend any significant amount of time here). They are not useless, because anybody that has the time will probably do some research on the company, organization or project to see what is up. At least this is what I do, and if it is something I believe in then I will start using, investing or playing (if it's a casino). Hard to say that they're useless, when they're doing exactly as they are intended to.
