Stolen account from 2012

So basically in 2012 my account named js5 got stolen by a user named spotbdog7889. Every time I tried to contact Roblox trying to get the account back, they said that I didn’t show enough evidence that the js5 account belonged to me. However I was just looking at my old archived messages and found some conversations I had with the account stealer. If I was to contact Roblox showing them all the messages with the stealer, would it be enough to get the account back?
