I prefer the way their campaign make expansion slowly but sure rather than huge expansion at one time and then remove the users who're part of huge expansion, moreover the old participants also get removed because they want to deduct the participants.
Yeah, everyone likes steady and reliable campaigns where you can participate for a long time without fear of any sudden changes. I think there was some discussion before where a lot of people said that they would prefer a slightly lower pay in a stable and predictable campaign over a higher pay in an unpredictable one.
Speaking of which, what is the minimum pay (per post or weekly) you would be willing to accept, i.e. what's the threshold below which you would say it's no longer worth it?
