Can my accounts be banned?

No

 

Edit: I misunderstood, thought this was about RM accounts

 

Correct. Jagex will only ban the account you botted on.

 

Unless, potentially, you swap a lot of resources between them.

 

I thought they didnt ban when you transferred stuff from bot.. Ive sent a few mill from my bot alt to my non botted main hopefully they both dont get the ban hammer... ive had my main since 2005

 

Unless you transfer billions of gp it's fine

 

had like 3 crappy bots banned on the same ip and same cache and main + other bot is untouched.
