It is hard to take if a member is removed from a campaign that they enjoy advertising, but take note that every campaign manager reserves the right to remove participants without warning or notice and you can find that information in the rules of every campaign thread.
I know that all the campaigns have that warning but one thing the managements have to know is that the participants are not robots but humans who use their brains and also have other works in real life. So they are sometimes they might produce low and high. There are sometimes a participant might not even know what he is writing, and many reputable members have also testified to this. As I said earlier, some managers understand those things and give warning from one to two and if the user is still on low quality then he or she would be kick out. And one thing we have to know is that mistake must come the matter the person is knowledgeable and brilliant. Well forum frown at low quality and there are different ways low quality post can be produced. And everyone view post from different perspective.
