And what really has value is this forum, not the users who rent their signature. Just go to altcoinstalks and see how much they will pay for the same posters signature. So the manager can just hire someone else with more respect for the company.
It is still quite important.
If users wearing signatures do not bring a positive impact to the company/service they represent, owners will certainly close the campaign with full rights. I will repeat, signature payments are not some money in the pile that we just need to take. It is someone's investment in promotion.

Speaking of examples, imagine a football club that has signed a sponsorship contract with Adidas, and then one player goes out on the field wearing Nike football boots.
