Try not to use completely fresh accounts, be ahead of yourself, use rested accounts and while your first lot are botting have some resting also.
ip's that have never played rs before get flagged easily, play legit for a little while first if possible.
be wise with your botting hours, mix it up, trail and error bans and what best suits your experience and you can find out what works best for you.
Don't keep using the same ip if you're getting banned
