I personally feel that users in a campaign should respect the company that hired them and make a post here and there in a company thread, but as multiple others have said, you cannot force or ask that of the users. Think of it as job protection, the more exposure a company feels they are getting, the more likely they are to keep a campaign going.
^^ Exactly this! The company pays all the participants in the campaign, and the company wants to keep their thread active and visible. Anyone with half a brain cell should put two and two together.
I think it is at least polite to write something in their main topic from time to time, regardless of the fact that you are not required to do so.
Uh huh, that's why you are hiding behind an alt like a pussy.
Good point there.
