Call your service provider and ask for a new ip. Fuck using proxies or VPNs, a lot of them are flagged already. Also reset your hardware ID. Malle made a guide on it and ever since I did it I swear my bans have cut way down.
1. No proxies or VPNs 2. Mirror mode only 3. Combat seems to have a lower ban rate then any skill from my experience 4. Delete jagex cache and Random.dat file 5. Only use scripts that have a great reputation (Czar da man) Good luck/Goodbye buddy
