i myself have played RS from 2002 on and off and have botted from about 2005, and no changing your IP does not change the mac "A MAC address is a unique identifier for a device on a local network, and is usually permanent. It's assigned to the device's network interface card (NIC) " yes it can be spoofed but not changed unless you get a new route every time you do it. and you say you botted 4 hours on old account and got banned yet here is me botting accounts up to 10+ hours a day with no bans at all, 99 magic from 66 in less than 2 week, 4 account with all over 75+ agl now all botted more than 4 hours a day, so there is some think you are doing to get banned so fast you my not think you are but there has be more than just the client as other have said people are using OSbot for bot farms and doing fine but you on the other hand seem to get banned like mad! and i said about being able to bot before EOC happened as jagex were said not to ban bots for a full year to try and work on making them go away (didn't happen with EOC at all), and just so you know its a AI that flags accounts so they see stuff people will not and pick up on patterns fast.
and one last thing you know why you hear more about people getting banned? because people dont moan when and go tell everyone when stuff is going the way they wish but as soon as shit goes tits up they moan about it to everyone they can.
PS i looked up to see if sandboxie changed HWID as i know it didn't when i was using it but that my have changed over time but nope it does not this is a reply from a mod on there forums too someone asking if it does
"Right now, there is no function to change a HwID. Sandboxie-Plus 1.14.7 will include HideNetworkAdapterMAC, HideDiskSerialNumber and RandomRegUID. Those features will reduce some fingerprinting vectors, but a machine should remain identifiable. Privacy was not a design goal, as far as I can tell, but it's nice to have."
