Alternate account detection

[iloveyou_bud]

I tried to join Perris then it kicked me out and said "SERVER ALTERNATE DETECTION BY MOUTAIN INTERACTIVE CORP."
This is my main account and i don't have any alt accounts.
Here is my profile Link: https://www.roblox.com/users/2432624468/profile

So if your being denied entry to our game you have more than 1 alternate Roblox created and that is prohibited here. You must link your main account and only use that and you may still have trouble as there is a system to prevent alternative accounts.
