If you're leaving the forum and you've claimed you aren't ripping BigBitz off, you should pay him back. There's nothing to lose for you since you're not using your account anymore, so it comes down to whether all the threads you've made are true or not. BigBitz came to a resolution with you on the amount of payment, so it's now your choice of what you want to be remembered as here and around the internet.
It has been my experience over the past years that when people make public claims of "leaving the forum" it usually means one of few things.
1) I am faking it to have some one ask why?
2) I have several alts and don't care about this name.
3) I will be back.

It'd make sense since he's drawing so much attention to his King of Sports account and making a KoS2 account that he'd have another username he's going under (Also since he's been talking about all the business ideas he was going to start up), and is just trying to draw attention away from everything else until this all blows over.
