How do you feel about that? Do you think it is OK that you just advertised a service for free and weren't selected in the campaign in the end?
As a user; I don't consider that an advertisement instead a requirement to be considered in the first place for the Job. I don't think anyone should consider that an advertisement if it's required to wear before getting a slot at your account been reviewed. If I'm not in a campaign, I wear the ads of whatever company I'm applying for before even dropping my applications and when I'm in a campaign, even though the manager stressed the wearing of avatar and signature part, I still apply because I know what I can offer. If it's someone I haven't worked with, I'll just simply leave a note of updating those ads if I'm been hired.
From the aspect of a manager; Actually majority of the applicants don't really care for the free advertisment of a thing. Some can even keep wearing your ads until another opportunity present itself for them to get hired. Nobody is forcing them to wear the ad but it'll just be easier so avoid hiring users that aren't not wearing the ads. I did manage a campaign that I had to disqualified 3/4 users that weren't wearing the ad although they have been accepted. Some users apply in so many campaign that they take the slot meant for other and make project lose days of publicity. Hope you understand what I'm trying to mean here.
