I think you're oversimplifying it here. If the rules are not clear and the participants did the work, then they are scamming users by just kicking them out without an explanation.
It is their right to have rules and not pay based on those rules, but if the rules are not posted how can they expect users to comply with them? There's interpreting a rule incorrectly and there's breaking a rule but in this case looks like there were no rules to comply with.
I remember the time when you ran many campaigns on the forum, you had very clear rules. Nevertheless, despite this, there were many complaints and those who were dissatisfied.
Tagged the company for now as I see the manager/owner has been online and hasn't replied yet. Willing to revise the tag if they explain themselves.
Pm also sent to cryptomus so they know about this topic
I'm almost certain it's a waste of time. Obviously, they don't know much about the forum and some basics of how things work here. They had received some useful advice before, but they somehow skipped over to see it.
