I believe that even the campaign is in testing phase (one-week test first), and give low payment rates, it will show positive changes in the way users from Africa continents compose, and publish their posts/ topics next weeks, at least one.
The payment rates are low, for someone who come from developed nations, but in African nations, I think it makes sense for locals there. Additionally, it gives them motivations to grow up faster with decent posts and constructive topics.
Campaigns are always there, they opened and close from time to time, and chances to join high payment-rate campaigns are opened for everyone.
Let's grow up, improve your quality, your contributions, build up your accounts, sometimes you can join highly payment-rate campaigns for sure, African users.
As you can see within recent weeks, there are some good paid campaigns opened, but there is no chance for airdropped higher rank users to join.
Those campaigns' managers tend to accept self-made users.
I think that the forum has jumped into new era, the era of self-made users.
Higher rank users will only be able to join shitty campaigns, if they even can not earn 5, 10, or 20 merits more than one year after the merit system's birthday.
You made good initiatives to design avatars for the campaign, I appreciated your contributions to @CryptopreneurBrainboss's campaign.
However, I have small suggestion for you.
Due to the reality that signatures of the campaign tend to use Green-colored theme, so I thought that it should be better for the campaign in general if it can stick to basic Green-colored theme, for both signatures and avatar.
In short, I think it should be better if you spend a bit of time to re-design the avatar to switch its theme to Green-colored.
Additionally, Africans tend to prefer bright colors, like Green, Red, Yellow, so why not redesign both signature and avatar with main colors are Red and Yellow, that are closer to the background of safaris, that are familiar with Africans?
If not
Green, so why not try with
Red, and
Yellow?
Of course, let's wait to see the opinion of the OP.
