Hey bud, welcome to our forums! Regarding your banned 2k total RS3 account, since it was such a long time ago, you can try sending in an appeal request here https://support.runescape.com/hc/en-gb/articles/360000867958-Appeal-a-ban as old accounts have a chance at getting unbanned assuming you did not break any serious rules in the duration on other accounts.
Hopefully you've learned from your mistakes by now. Gl and see you around!
