As I use to be apart of the botting community I can provide some insight :-)
Most ban waves occur during/after the weekly update. Whether it's rs3 or osrs this does not change.
For RS3 we've found it you have a longer account survival rate if you perform your bot action in an instanced area. This way players cannot report you.
As per OSRS, we cannot confirm whether this helps or not.
Stay away from VPNs/Proxys as you will stick out like a sore thumb. It's always recommended to delete your game cache after experiencing a ban as well.
