I wonder why Stunna still hasn't commented on it.
Could perhaps that Stunna is tracking this guy now secretly that he doesnt want hufflepuff to feel insecure about this. Another theory would be that the exploit hasnt been fixed yet and commenting on it will lead people to try it and again manage to get it
The second is highly unlikely. Stunna would rather close the site than let it continue with the exploit, as Hufflepuff can always come back through another account and repeat the process in the same way like before.
As for tracking, I doubt it . Even if thats the case, he can always leave an update, which wouldn't interfere with anything that he might be doing.
