This question has occured to me many times but
What makes members move everytime? I need your contribution on this to make me understand it better.
It depends on every individual’s perception, we may have different view of signature campaign and what may drive me to change from one campaign to another will be different from yours but I believe most people are influenced by the pay rates just as _act_ have mentioned. When ever a new campaign with higher pay rates is launched a lot of people will leave their campaign just to join that campaign but not everyone is joining because of the high pay rate.
Change of campaign rule: When the rules of the campaign change, it might not suit some members. Some campaigns can decide to remove or add some boards to their campaign posts which some members might not be comfortable with
This is also one of the major reason why some people change campaigns, the post requirement for some campaign may be too much for some members to cope, they may be too occupied to have enough time to carry out the required number of post and so they will be seeking to join campaign with lower post quota. There are also people who are not convenient to post in some boards like how some campaigns demand for 10 gambling posts for the week and when they don’t have much knowledge about gambling discussions they will seek for campaigns that doesn’t make it mandatory to make gambling posts.
Longevity of the campaign: Some members might decide to leave a high-paying campaign to a lesser one because they believe that the low-paying one will last longer. Some members cherish longtime campaigns rather than high-paying ones.
This is another aspect that individuals take into account while switching from one campaign to another. Some people choose long-running campaigns because they believe they are more secure in the long run. We've observed some high-rate efforts that didn't survive as long as anticipated, yet their members kept switching to the campaigns that paid less.
The reputation of the campaign manager and how strictly the manager runs the campaign are other reasons why people switch to other campaigns. People will rather participate in a campaign where they will feel secure and have peace of mind.
