I mean it depends what your goal is from the accounts. It seems to be a woodcutting bot if I'm not mistaken. Do you want to get 99 or max it as an account to sell? Or is it for the gp? Depending on your priorities either bot it until it gets banned or play it safe to level it up.
Congrats on your script, however to be fair if you are only running one script I don't believe the sample size is large enough to conclude that your script is purely safe. There can be times when accounts don't get banned and other times where they constantly getting banned.
There is always a chance to be banned no matter what account you use or what script you use. If you are willing to lose it don't bot on it. With that being said if you feel you are competent in coding then making your own script would probably be safer as you may be using different methods as other scripters. However if you aren't sure there are lots of good public scripts that are out there. Just remember if you are afraid to lose it don't bot on it!
If you're looking for a multibox sort of thing where with one main account you can control other accounts I know Script Factory Pro has that function otherwise you may want to refer to what @Gunmanhas said.
Ah got you even when I use Runelite I usually just have the default plugins active so I rotate the camera around a lot if I'm being completely honest lol !
Generally speaking the plugin is pretty bad at actually seeing if an account is a bot. I know of people who have mains that are called bots while I know botters that have accounts that are considered legitimate players. As long as you aren't essentially level 3 with a bot username sitting at willows in draynor 24 hours a day you should be fine. The bot buster plugin is really all over the place and is essentially random.
