The stakes depends on the signature space.
The space provided by senior member and hero members are more visible and bigger than the lower ranks.
When I was also new to the forum, I also noticed that but I don't know the history of it, probably that's it.
That caused by you need more effort to make or increase your rank from the newbie to the legendary. The history of stake created by the old system of BTT that gave you 14 weekly activity and you need a certain amount of your activity point to make you able to increase your rank. That's why there was a stake allocation based on level.
The thing you mentioned is about the old activity and rank upgrade.
I can't see the relation of it from why advertisers pays higher stake for higher ranks. And my explanation is likely to be the reason why they pay for good for higher ranks, due to the signature space and color, characters that it can provide.
I agree with you. I've been here 1 year before i became active and I have to be honest -- it's because of bounty ,though I never joined any spammer campaign be it here or in social media, not that it matter but just saying
. Unfortunately, when we had the merit system I was only on member level. Been doing bounty for 1 year now and looking back, I realized that I didn't have any successful ( significant reward ) Signature campaign. Maybe, on the back of my mind is the same reason what the author posted and i felt like i'm ONLY going to get that LITTLE chunk anyway. All Sig Campaigns I've seen would require the same amount of posts for all types of levels and yet there is a very big differences with the rewards. It's a bitter truth to swallow, i just need to suck it up I guess.
