@LL seemed to have health issues so he can't continue to be active which resulted in a piling of unpaid weeks so brainboss decided to put the campaign on hold, now things changed the payment funds are in the hands of the manager so there will be payout every week just like any other campaign.
I wasn't involved in that campaign, but reading LL's trust ratings and reputation thread, it doesn't look like it was a single case of delay (possibly caused by health issues), but rather multiple issues with payment delays lasting weeks. But that's why it's good to have a trusted manager holding funds in escrow.
Also, it is good to see the increased payout which is still low compared to other campaigns
Yup, if I'm not mistaken, even after the increase, it's still max $1/post (and only for the top-tier), which makes it the lowest-paying campaign among the currently active ones. But still, if there are takers, then why not? Offering low payments and adjusting it up later, if needed, is a pretty sensible way of making sure the campaign organiser is getting the most of their money. But again, it could backfire if the manager is not active in fighting low quality spam.
