Are you kidding me? the campaign is already over mate.. the world (FIN) stands for finished.
try to apply on campaigns that are open right now, there's still more in the same section.
and by the way, 500 is not an earned merit, merit/s after 500, those are considered earned.
Quite funny, the account was last active last year in November. It looks like an alt account that is just used for signature campaigns.
But I think they lack the funds to continue the promotion and of course this is an inevitable problem for every developer if it does not reach the target to be achieved.
I doubt if it was due to lack of funds because of the number of members and payment rates they were offering. If money was less, they could have started with fewer users.
Unfortunately a campaign that just takes only a week is more like no work done because as soon as it closes, people remove signatures... I feel this long term campaigns benefit a lot from exposure compared to ones that just keep closing up after short periods of time.
