I believe there was a time the Stake manager Carollzinha updated Stake campaign rules and included a rule that prohibits Stake participants from using AI. If such a rule is still being recognised by her, she should therefore remove anyone proven to use the forum with AI.

As of neutral tags or negative tags, it is at the manager's discretion to choose who will promote her project, especially if the tags are not related to scam. Sometimes inaccurate ratings are given, so the manager should decide the severity of each tag and act to the best interest of the project.
