most probable explanations: 1: someone bruteforced admin and the account became active (recent logins still show when you're terminated) 2: roblox reopened the account for a new moderation system, reusing the account for its original intended purpose
I don’t think Admin Was Actually terminated I think his hidden and they pretend that he was actually terminated because why is he active on Roblox because when you are terminated you can’t go back on Roblox.
