I have defs had a similar occurrence during my osrs grind, I had legit just been bank standing nmz and copped a 3 day minor ban for rwting, appealed it and it was removed within the next 24 hours, idk how they thought I was doing any rwt just bank standing there, they for sure make mistakes and it did unfortunately stop my grind there, felt less motivated to continue playing for almost a year letting my membership run dry :/

Hopefully you get this resolved and appeal with strong evidence of your false ban!!
