Okay, so I've committed things that were against the rules in relation to my account. After I was sure I was done playing, I gave the RS gold account away. Recently, I unsuccessfully tried to get it back. Jagex has not responded to me. I have emailed Jagex numerous times. The email address registered to Jagex's account (which was mine) was altered over a decade time ago. Therefore, it is expected that I should not receive any email.
However this morning, I received an email (legal (at) jagex.com). They informed me that they had evidence of me trading runescape accounts or things in real life. Okay, it's true. (By the majority, I have not purchased anything. Not too important, just want to inform people that I'm not smart enough to do that) They said cheap RuneScape gold they'd be watching my account and, if it persisted, I would be subject to an action for.
