I've always thought that posters should consider posting in a company's announcement thread or topic but knew that managers could not pay them for doing so or ask them to do so.
I agree.
Good participants should do research about the company, the platform they are hired in campaigns in order to understand about the platform and its products. At the end, with basic understanding, they will be able to
- Know that company is legit or scam
- Support the company with their proactive creative idea to improve platform, products; make proposals; and inform the team about bugs, typoes they find
These things should be done naturally to increase probability of success for the campaign and the business. It would be better for all related sides: company, campaign manager and campaign participants.
