The similarities in account information are likely because we are family members and I may have helped during the account creation process. At the time my sister created the Lotto accounts, neither of us expected that she would continue playing the game long-term or return to it after quitting. Honestly, I did not expect that I would still be playing Royals this much either. However, our actual gameplay and account usage were separate. That is likely why some account information appears similar while other details do not. The reason some email information appears similar while some does not may simply be because, when registering on Royals, clicking the email field often shows frequently used email addresses automatically, so she may have just used one of those. There was no separate verification required. However, this is only my assumption. It is also possible that I told her she could use my email address when creating Lotto or Lotto2, but this happened over 4–5 years ago, so I honestly do not remember clearly anymore. As for Lotto3 or 33, I do not remember those accounts at all. Because of that, I assume they may have been accounts she briefly created but never seriously used. The only accounts of hers that I clearly remember are Lotto and Lotto2, which were an Ice/Lightning Mage and a Bowmaster.
I do not even know which accounts contain the characters with the IGN names Lotto3 and 33, but they were most likely owned by my sister, as they were not part of any account series associated with the IGNs I listed above.
Her forum ign is ysk. She had her own separate forum account as well. As far as I remember, she created the forum account because posting on the forum was required in order to join the New Planet guild. I just went through all of the New Planet guild application posts in order to find it. Other than that, she most likely did not use it at all. Nowadays the New Planet guild rules are more flexible, so family members or acquaintances can join without making a forum post. However, at that time, when Sparky was the guild master, everyone was required to leave a reply on the forum in order to join the guild, so she created an account for that purpose as well. Similarly, some account information may appear similar, but the actual usage history of that forum account would have been extremely limited.
