I've appealed my main account (2k+ total) before and I got denied twice. The first appeal a JMOD replied saying that the ban was not applied incorrectly, second appeal was automatically denied.
The first appeal I lied and said the account was hijacked, second appeal I admitted to using scripts.
From personal experience and what I've read online, some accounts will get unbanned after a 2-3 year period if you're lucky. This happened to one of my accounts back in 2015 without submitting any appeal but some say it happens if you submit an appeal after 3 years.
Most likely you're shit out of luck though, as of recent Jagex seems to be way harsher when it comes to punishing RWT and macroing. If you want any hopes of getting the account back I would wait 3 years before submitting an appeal and in that appeal be completely honest and apologize.
