By the way, If you do these is because the threshold signature campaign 25 post/weeks are hard for you. The decision is on you too, you can leave the campaign and joined a campaign with paid-per-post without threshold post to be paid. You have a free time to post anytime you want, and you still getting paid what you post without any pressure at all from the minimum post to be qualified you getting paid.
The campaign in question doesn't have and never had a minimum post threshold:
3. There is no minimum number of posts that need to be written. We will pay up to 25 posts per week. Cut-off time is Sunday at 7 PM forum time.
Also cleared by @Trofo here:
We don't even have minimum post requirements in our campaign. 5 good posts per week would be fine by us but that means just 20$ payment instead of 100$.
