I don't know, probably a troll or a online bully/cyberbully. If I made them, my alt account would be useless because of IP block. But, those accounts likely belong to one person, because they acted the same way. And I couldn't revert their edits, since I had no alt account like Coronaverse or UniversePoker777 II. And, my IP is not blocked in AD wiki, that's why I made my alt account to help AD.
