I was just exploring the bounty campaign spreadsheet of Kleks Academy managed by a bounty detective. One unusual pattern got my attention. Looks at the screenshot below. All the username pattern looks the same. Their entry submission timing is also weird. It looks like one group was working together or all those ids belong to one person. I haven't looked at their trust score and didn't further investigate. If anyone wants can investigate these ids. Here is the spreadsheet link. Those are from the article section.
