We're talking about a purge not taking a freed up name on another sever. And If it was a name like Yehgnii-Stahshen, I guarantee you that's never happened yes. Even if someone were fascinated by Yehgnii-Stahshen they'd still have to wait two years, have Yehgnii-Stahshen not be L30 and have Yehgnii-Stahshen be inactive for the past 60-180 days prior to the purge.
Don't worry about Yehgnii-Stahshen.
