I botted hunter 16 hours straight on my 14 years old account and got only 1 day ban. Do you think because this is a old account and not a new one ? If it was a new one would I get immediately ban ?
At this point I think Jagex has different weights that go into the equation, but it's still random. I wouldn't be surprised if they have a daily quota of bans and go harder when the numbers are low and lighter when they already hit it. You should watch the recent video that explains how they weigh bans:
